ABSTRACT:
The invention pertains to a theftproofing system for motor vehicles with a locking member which can be engaged in a recess of a closing ring arranged concentrically to a steering shaft (9) and firmly connected to it and, when the locking member is engaged, blocks the steering shaft until a limiting torque is introduced into it.
According to the invention, it is proposed that, in the frictional connection between the steering wheel (steering wheel spoke 5) and steering shaft, a slip clutch (3, 4, 8) be provided whose transmittable torque is lower than the limiting torque.
