Claim:
An antitheft steering lock device comprising: an antitheft lock body comprising: a first portion comprising locking means capable of immobilizing a movable steering element, and a second portion, wherein a lock cylinder is inserted and positively connected inside the second portion, and wherein the lock cylinder is capable of controlling the use of the locking means; and blocking means, distinct from the locking means, capable of inhibiting the use of the locking means when the lock cylinder is removed after the lock cylinder has been positively connected inside the second portion of the antitheft lock body, wherein the blocking means comprise: an immobilization element mounted so as to be movable between a passive position in which the immobilization element is placed at a distance from a movable element of the locking means, and an active position in which it interacts via immobilizing contact with said movable element of the locking means to immobilize the movable steering element; elastic return means capable of moving the immobilization element into the active position; and a removable retention element that toggles the immobilization element between the passive position and the active position via an intermediate rod, and that is capable of being irreversibly coupled to a stator portion of the lock cylinder when said lock cylinder is positively connected in the second portion of the antitheft lock body, and wherein the removal of the removable retention element, during removal of the lock cylinder, is capable of releasing the mobility of the immobilization element from the passive position to the active position, wherein said movable element immobilizes the movable steering element, and wherein a length of the intermediate rod is perpendicular to a length of the removable retention element.
