Theft protection cable and circuit including said cable
First Claim
1. A theft protected electric cable comprising a conducting core, an insulating sheath surrounding the core and connection means, said cable being connected between an electric source and a user member by means of at least one contactor, the contactor comprising a housing, a first electrically conducting member and a second electrically conducting member in contact with the core, one of the conducting members being slidable within the housing between a first position wherein electrical current flows between the conducting members and a second position wherein no electrical current can flow between the conducting members, said core being permanently under mechanical tension to establish a mechanical and electrical contact between the conducting members, the said housing including no return means to prohibit the movement of the slidable conductive member from its second position to its first position, whereby the passage of electric current between the conducting members after a break of the cable will be prevented.

Abstract
A theft protection electric cable includes at least one conducting core, a sheath which is least partially insulating, and a suitable connection. The cable is characterized in that it is connected between a source of electrical voltage and a user member by at least one contactor (3), said contactor receiving information concerning the conducting or non-conducting state of the cable and including a spring or switch (11, 34) for interrupting the passage of electricity as a function of said information.

- 9. Theft A theft protection device for an automobile having an ignition distributor including a cable, a core, and a sheath characterized in that the sheath (2) is removably mounted on the end of the ignition distributor (39) of the type having a skirt, the core of the device being fixed to the skirt (34) to establish contact between the core (1) and a conducting area (10) of the distributor head while compressing a spring (11), so long as the sheath is properly mounted, with locking means (53, 55) preventing contact from being re-established after the mounting of the sheath is disturbed.
