A motor vehicle steering lock is secured on a hollow outer steering column (3) enclosing the steering shaft (2) of the vehicle by means of a yoke (10) engaging around the steering column (3) on the side remote from the steering lock housing (5). The yoke (10) is screwed to the steering lock housing (5) on both sides of the steering column (3) by a respective break-off screw (18, 19). Each break-off screw (18,19) is secured against being unscrewed out of its threaded bore (22, 23) by a security pin (28, 29). Each security pin is inserted in a respective bore (30, 31) in the steering lock housing (5) running perpendicular to the threaded bore (22, 23) and intersecting the threaded bore (22, 23) tangentially, in order to extend tangentially through a respective annular groove (34, 35) in the break-off screw (18, 19). Each security pin (22, 23) has its inner end (36, 37) engaging in a bore (32, 33) in the steering column (3).
