The socket and plug parts (2,3) of the couplings engage in each other without ball locks. The sleeve socket part (2) is fixed with an outwardly projecting circumferential flange (14) countersunk in a corresponding circumferential groove (15) on an assembly opening on the fixed support plate (4) so that it closes with its flat end side (17) in a common plane with the coupling side of the plate (4). The plug parts (3) of the couplings are rigidly fixed on the movable support plate (5) and project far enough from same so that the two support plates (4,5) sealingly adjoining each other in the coupled state. The lower fixed support plate (4) pref. has a slightly larger dia. than the movable upper support plate (5) and is flatted round the sides in the area of the tension levers so that the latter hold the tension pins protruding sideways from the movable support plate (5) in curved engagement slits inside the circumference of the fixed support plate.
