A device for preventing rotation of the steering column body of an automobile vehicle comprising a support member attached to the chassis of the vehicle and a body which is held in position relative to the support member by a locking system. For the adjustment of the steering column concerned in the required direction at least one pair of coupling surfaces is joined to the support member and cooperate with a pair of coupling surfaces joined to the body. The coupling surfaces have a direction substantially parallel to the required adjustment direction and are angularly oriented with respect to major faces of the support member and the body, so that the coupling surfaces cooperate with each other upon locking in order to prevent rotation of the steering column body.

A device for coupling two shafts rotatable about a common axis comprises teeth at the end of one shaft and notches at the end of the other shaft. The teeth and the notches have conjugate profiles and inclined sides so that the teeth engage in the notches. An axial retention sleeve surrounds the ends of the two shafts and has bearing end faces substantially perpendicular to the common axis. A compression spring bears on one of the bearing end faces of the sleeve coupled axially to one of the two shafts and presses the ends of the two shafts against the other bearing end face of the sleeve.
