A gas sensor is known, for example, from German Patent Application No. 41 26 378. With the known design, two contact shells in which the electric contact parts are mechanically secured are pressed against the contact points of the sensor element by a horseshoe-shaped or hexagonal spring element which is open at one end. A spring element (spring clip) which is also clipped on it ensures the vibrational strength of this design. However, when more than six terminals are provided on the sensor, secure contact for all contact points is no longer guaranteed. In addition, the installation space would be too small due to the additional space required for the mechanical anchoring of the contacts.
