<p>The invention relates to a security antitheft device including a housing (1) in which a rotor (2) is rotatingly mounted between an angular rest position, said cam being capable of interaction with a control spigot (140) supported by a slider (100) capable of sliding in the housing in an axial direction, between a rear position of the antitheft device towards which it is urged by elastic means (110) and in which it axially protrudes towards the rear through an opening in the housing for controlling the rotational locking of a member of the steering column when the rotor is in a rest position with the key removed, and a front position in which it is stowed inside the housing, characterised in that it further comprises a device for positioning the slider including a follower (4) in the vicinity of the rotor input so that it can be urged by the key as soon as it is introduced into said rotor, the slider comprising a body (100) with an elongated shape, a blade having its rear end connected at least in translation with the body of the slider so that the front end of said blade co-operates with the follower and is capable of radial displacement, and elastic means for radially urging the front end of the blade towards the centre or the rotor.</p> |
