An anti-theft device for a motor vehicle comprises a flexible cable (12) disposable between an ignition key operated steering column lock and a rotary electrical ignition switch (16) for transmitting rotational movement of the ignition key to the rotary switch (16) during normal operation and enabling the switch (16) to be disposed at an inaccessible location remote from the steering column lock. One end of the cable (12) is normally coupled to the rotary switch (16) by way of a spring biased piston (50) having a projecting member (52) drivingly engaging a recess (54) on the switch (16). Should the connection of the cable (12) with the steering column lock be broken, eg by tampering, the spring (48) biasing the piston (50) acts to separate the projecting member (52) from the switch and thereby break the rotary coupling between the cable and switch. A spring loaded detent (68) prevents reengagement of the piston (50) with the switch (16). <IMAGE> |
