A steering apparatus assembly, having a steering axis, about which the steering apparatus assembly can rotate in is disclosed. The steering apparatus assembly comprises a first element and a second element. The two elements are connected to one another by a first and second joints. The first joint comprises a resilient locking element, which is deflectable in a direction transverse to the steering axis to disengage the first joint. The second joint is deflectable by an axial load acting on the assembly elements away from one another. A wedge is provided having a wedge length transverse to the steering axis and a variable wedge height in the direction of the steering axis. The wedge length and length and a wedge inclination angle are matched to one another such that both the first joint and the second joint can be undone by a linear movement of the wedge in the longitudinal direction.
