Abstract
An anti-theft steering lock includes a locking sleeve fixed to a steering shaft and having substantially radial teeth. Pivoted levers each having a pointed tip are freely pivoted on axes extending parallel to the steering shaft and fixed to a fixed support in which cradle portions are formed. The levers are nested in these cradle portions. Second ends of the levers, opposed to the pointed tip ends, cooperate with a window formed in a control bracket which has a narrow zone and a wide zone. The angular spacing between the pointed tips of the levers is slightly smaller than the angular spacing (a) between two successive teeth of the locking sleeve, or a whole number multiple of this angular spacing.
