A connecting wedge is connected to the connecting piece, in which two pins extending perpendicularly to the longitudinal direction of the wedge and being guided in the connecting piece are mounted. An adjusting element is connected to the connecting piece, by means of which the connecting wedge can be moved in a direction transversely to its longitudinal direction. The connecting piece comprises a screw spindle, which is journalled in the connecting wedge and which is screw into a nut-shaped member connected to the connecting piece.
