     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     With reference now to the drawings, and in particular, to FIG. 1-6 thereof, the preferred embodiment of the new and improved seat belt safety alarm embodying the principles and concepts of the present invention and generally designated by the reference number 10 will be described. 
     Specifically, it will be noted in the various Figures that the device relates to a new and improved seat belt safety alarm for preventing a child from disengaging a seat belt. In its broadest context, the device consists of a housing, a clamp, a battery, a circuit board, a speaker, a tongue, a rheostat, and a sensor switch. Such components are individually configured and correlated with respect to each other so as to attain the desired objective. 
     The first component of the device 10 is a housing 12. The housing 12 has a front 14, a rear 16, a top 18, a bottom 20, a left side 22, a right side 24, and an interior 26. The left side 22 has a slotted opening 28 therein. The interior 26 has a heel 30 secured therein adjacent to the slotted opening 28. The slotted opening 28 is adapted to receive an existing seat belt tongue 32 therein with the tongue 32 fitting over the heel 30. The interior 26 has a ledge 34 secured therein disposed above the slotted opening 28. The interior 26 has a wall 36 therein inwardly of the heel 30. The right side 24 has an opening formed therein. The opening has a door 38 removably coupled thereto. The housing 12 is also equipped with a padded outer layer 40 to protect a child from discomfort while the device 10 is being used. 
     The second component of the device 10 is a clamp 44. The clamp 44 has a first end 46 and a second end 48. The first end 46 is secured within the top 18 of the housing 12. The second end 48 extends into the interior 26 of the housing 12 through the ledge 34 thereof. The second end 48 has a plate 50 secured thereto. The clamp 44 adjusts the plate 50 up or down between the ledge 34 and the heel 30 of the housing 12. The clamp&#39;s 44 primary function is to secure the existing seat belt tongue 32 to the heel 30. This is simply accomplished because the first end 46 of the clamp 44 resembles a screw, therefore, one would simply take a screwdriver to tighten the plate 50 against the heel 30 with the existing seat belt tongue sandwiched in between the two. 
     The third component of the device 10 is a battery 54. The battery 54 is secured within the opening formed in the right side 24 of the housing 12. The battery 54 is the only power source for the device 10 and can simply changed when needed simply by removing the door 38 to gain access to the interior 26 of the housing 12. 
     The fourth component of the device 10 is a circuit board 58. The circuit board 58 is secured within the interior 26 of the housing 12 disposed above the battery 54. The circuit board 58 has a wire 60 electrically coupled with the battery 54. The circuit board 58 has a sensitivity adjustment screw 62 extending outwardly of the top 18 of the housing 12. The circuit board 58 is programmed with a variety of sounds ranging from low pitch to high pitch. The sensitivity adjustment screw 62 allows a parent to simply adjust how loud of a pitch that they require with a screwdriver. 
     The fifth component of the device 10 is a speaker 66. The speaker 66 is secured within the top 18 of the housing 12 disposed above the circuit board 58. The speaker 66 has wires 68 coupled to the circuit board 58. The speaker 66 transmits an audio signal from the circuit board 58. 
     The sixth component of the device 10 is a tongue 72. The tongue 72 is secured to the right side 24 of the housing 12. The tongue 72 has a first end 74 and a second end 76. The first end 74 is adapted for coupling with a seat belt buckle 78. The second end 76 extends within the interior 26 of the housing 12. The second end 76 has a U-shaped portion 80 secured thereto with a furthestmost portion 82 overlapping the wall 36 within the interior 26. The furthestmost portion 82 and the wall 36 have a spring 84 therebetween. The tongue 72 can be slid within the housing 12. The spring 84 causes the tongue 72 to return to its original position with the furthestmost portion 82 distanced from the wall 36. 
     The seventh component of the device 10 is a rheostat 88. The rheostat 88 is secured between the furthestmost portion 82 of the U-shaped portion 80 of the tongue 72 and the wall 36 of the interior 26. The rheostat 88 has a wire 90 coupled with the circuit board 58. The rheostat 88 sends a signal to the circuit board 58 when the tongue 72 is pulled on causing the furthestmost portion 82 to press against the rheostat 88. The harder the furthestmost portion 82 presses against the rheostat 88, the louder the signal that the circuit board 58 will transmit through the speaker 66. 
     The final component of the device 10 is a sensor switch 92. The sensor switch 92 is secured within the interior 26 against the right side 24 of the housing 12. The sensor switch 92 has a wire 94 coupled with the circuit board 58. The sensor switch 92 has a switch portion 96 extending outwardly of the right side 24 of the housing 12 disposed above the first end 74 of the tongue 72. When the tongue 72 is within the seat belt buckle 78 the switch portion 96 is biased inwardly. Once the seat belt buckle 78 is removed from the tongue 72, the switch portion 96 extends outwardly causing the sensor switch 92 to send a signal to the circuit board 58 which in turn transmits an alarming signal through the speaker 66. 
     As to the manner of usage and operation of the present invention, the same should be apparent from the above description. Accordingly, no further discussion relating to the manner of usage and operation will be provided. 
     With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and the manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention. 
     Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modification and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modification and equivalents may be resorted to, falling within the scope of the invention.
