ABSTRACT:
The invention relates to a security device, in particular an anti-theft device, of the type suitable for constraining the steering wheel to rotate with the steering column of a vehicle, or for allowing it to rotate relative thereto. According to the invention, the security device comprises a base secured to the steering column and surmounted by a central head; a box constrained to rotate with the steering wheel is mounted on the base and includes a guide passage in which a coupling slider is received free to move between a position in which it couples directly with the central head and uncoupled position, the slider being subjected to the action of springs tending to urge it towards its coupled position; a lock assembly is disposed in a secondary housing together with a cycle cylinder and a moving shaft, the shaft co-operates rates with an extension of the coupling slider to lock it in an uncoupled position or to release to take up the coupled position; and an external pusher arm makes it possible to return the slider into its uncoupled position.
