Abstract
A device is provided for making a firm but releasable joint between a steering wheel which is connected to the steering column and a locking bolt that is movable by means of a lock cylinder. In order to provide between the hub of the steering hub and the locking bolt a joint which cannot be forcibly released from the outside, the diecast steering wheel hub is pot-shaped on the side facing the steering column and its cylindrical flange which in concentric to the steering column is provided on its inside periphery with a multiplicity of axial grooves for receiving the locking bolt. A metal ring is provided in front of the end faces of the grooves and is firmly connected to the land disposed between the grooves.
