Abstract
The coupling (1) consists of two coupling parts (4, 5) which can be pivoted one inside the other for coupling. They can be locked and clamped in this position by means of two wedges which are arranged so as to be laterally displaceable in the top coupling part (5). For this purpose, the wedges are pushed in a diametrically opposed manner under the projections (13) by being moved by a common threaded rod having two opposed threads, which threaded rod passes through the wedges. The threaded rod is driven via a roller chain by a hydrostatic drive arranged in the top coupling part (5). <IMAGE>
