A quick-coupling assembly for fluid conduits and of the kind comprising a first sleeve-shaped member, which at one end is provided with a number of resilient tongues provided with at least one projection intended to be locked behind at least one shoulder or the like in a second sleeve-shaped member for being connected to this and a ring being actually displaceable in the second member towards and away from the shoulder and being designed to cooperate with the tongues for compressing these so that they can be moved past the shoulder. The object of the invention is to provide a quick-coupling which despite high pressures (e.g. 350 bar) is easily rotatable so that a pressure hose connected to the coupling really can rotate, which is especially important at many hydraulic arrangement where relative movements occur between different structural parts connected to each other by pressure hoses. This object has been solved by the fact that the shoulder (5) comprises a ring (10) which is rotatably but undisplaceably arranged with respect to the second sleeve-shaped member (4). |
