The drive bar (1) at least in the coupling area has a U-shaped cross-section, in the free parallel legs (4,5) of which on one side of the drive bar are inner teeth (6) and on the opposite side of the drive bar are outer teeth (7). In the outer areas of the legs before formation of the inner teeth parallel to the legs are outward stage-formed embossments (8).
