fig1 is a longitudinal section of a preferably synthetic plastics holder 1 , wherein a detection element 2 diagrammatically shown is embedded . at the bottom of the holder there is pivotally provided a flap 3 at one end at 4 , which flap serves for clamping one of the ends of a band 6 . in the closed position of the flap 3 shown , this is secured by lugs 5 ( see also fig2 ). for the purpose of clamping the free end of the band 6 , the flap 3 is fitted adjacent the pivoted end with a boss 7 which , in the closed position of the flap 3 , extends to adjacent a rib 8 of the holder 1 opposite to boss 7 . in the opened position of the flap 3 , the band end can be passed freely between the boss 7 and the rib 8 and be pulled underneath the responder 2 and again be conducted at the other end of the responder through a slot 9 in the holder in outward direction . in closing the flap , the band is fixedly clamped between the boss 7 and the rib 8 . the other end of the band ( at the right - hand side in the drawing ) has a looped form and is passed around a pin 10 installed in the holder , said pin being preferably designed as a shear pin . the embodiment shown in fig3 deviates from the embodiment shown in fig2 in that the flap 3 is fitted with a cavity for receiving the responder 2 . the responder may again be embedded in the cavity of the flap 3 and consequently be integral with the flap , but , as shown in fig3 may also be provided with retaining lugs 11 , which are adapted to detachably retain through snap action a loose responder block . the free band end in this embodiment is conducted along the top of the responder 2 . in the embodiment shown in fig4 and 5 , the responder 2 is embedded in a cavity of the holder 1 or detachably installed therein as a responder block . both ends of the band 6 with associated flaps 40 , 41 , which again are adapted for coaction with corresponding lugs 42 , 43 , can be fastened . to this effect , both band ends are inserted via slots 44 , 45 in the holder , while said ends come to lie on the responder or the responder block . above the slots 44 and 45 , being provided at the opposite ends of the holder , there are provided transverse ribs 46 , 47 of the holder , which are hollow at the bottom . in said cavities fit correspondingly curved half - round end edges 48 of the otherwise flat flaps , as shown in fig5 . the flaps , as shown by arrows 49 , can be swivelled upwardly with their flat ends , while the curved end edges turn in the cavities of the ribs . the band ends , in the upwardly turned position of the flaps , are inserted in the holder and subsequently clamped with the free edge of the curved end edges of the flaps against the lower edge of the slots 44 and 45 by bringing the flaps in the position shown . in order to increase the clamping effect , the free edges of the curved end edges of the flaps may be fitted with teeth 50 , as shown in fig5 . when in this embodiment a loose responder block is employed , the first portions of the flaps are so long that in the closed position they partly lie on the responder block , as shown in fig4 . the maximum band pull force that can be exerted without loosening the band , is determined by the strength of the half - round end edges 48 . fig6 and 7 show a variant of fig4 and 5 , in which the rotary flaps have been replaced by substantially flat slides 60 , each having an end edge 61 bent at an angle slightly more than 90 °. the ribs 62 of the holder corresponding to the ribs 46 , 47 are now flat at the bottom and , together with the opposite lower edges of the slots 44 , form a slightly wedge - shaped space accommodating the slides . the bent edge 61 of each slide is adapted for coaction with an ascending portion 63 of the lower edges of the slots 44 for clamping the band ends . to this effect , the bent edges 61 may again be fitted with teeth 64 , as shown in fig7 . when the band pull force exceeds a given value , the slide passes the ascending portion 63 . fig8 shows a variant , in which instead of a slide 60 , as shown in fig7 there is employed a wedge 80 fitted at the bottom with teeth . the maximum band pull force is now determined by the ribs 62 designed as shear pins . in this embodiment , furthermore the responder block 2 is detachably retained in the appropriate cavity in the holder by retaining lugs 81 , which are comparable with the retaining lugs 11 of fig3 . fig9 finally shows a variant in which the band ends are each provided between and about three ribs 90 , 91 and 92 integral with the holder and designed as shear pins . it is observed that after the foregoing , various modifications are obvious to one skilled in the art . for instance , the responder could be placed e . g . in a different position in the holder . such modifications are deemed not to depart from the scope of the invention .
a holder for an electronic detection element , which is adapted for attachment about the neck or other part of the body of an animal to be detected by a band . the holder is provided with a cavity for receiving the detection element and with at least one clamping member for adjustably clamping a band end .
