The cylindrical socket extends over at most 180° in the circumferential direction. The cylindrical head is provided with a radial thickened section which extends in the circumferential direction. The cylindrical socket is provided with a radial recess which extends in the circumferential direction and in which the radial thickened section can be accommodated, with the cylindrical head in bearing contact inside the cylindrical socket.
