Abstract: The steering lock for vehicles, more especially for motor cycles, comprises a lock reception housing which is secured to a tube of the vehicle steering shaft and in which there are arranged in an axially parallel manner a locking bolt to be introduced into the steering shaft and a cylinder lock so as to be axially displaceable and being connected, and comprises a cylinder housing, a cylinder core within the housing, a locking part which projects beyond the cylinder housing and can be introduced, for fixing the cylinder lock in the locking positions, into a recess of the lock reception housing.The locking part is a ring sector which, in the locking position, projects with one area into the recess of the lock reception housing in an interlocking manner and stays with the remaining area in a recess of the locking bolt, which recess receives the ring sector in the displaced position and comprises a surface which is vertical to the locking bolt longitudinal axis.

Abstract: The device serves to lock the locking bolt of a cylinder lock in its locking position when an unauthorized removal of the locking cylinder is effected. A lever mounted with the housing of the cylinder lock rests against a portion of the locking cylinder which effects swivelling of the lever upon the removal of the locking cylinder. The locking bolt is lockable by a locking piece which is spring-loaded in the direction of the locking position and is held in the unlocking position by the lever in the non-swivelled state thereof. The locking piece is released when the lever has been swivelled by the locking cylinder.
