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.
