ABSTRACT:
A coupling for rapidly and detachably connecting a conduit pipe or hose to an opening is disclosed provided with an inner sleeve having a flange on at least one end, an outer sleeve capable of moving with little play about the inner sleeve, a groove for a flexible sealing member between the coupling and the opening to be connected as well as clamping means for the relative axial movement of inner and outer sleeve and for pressing the sealing member tightly into the opening, whereby the inner sleeve is provided near the flange with an inclined ascending face which can mate with a corresponding ascending face at the outer sleeve, the outer sleeve being furnished with a groove arranged all around it for accommodating a sealing ring, while at least the part of the outer sleeve in the zone of the nest for the sealing ring is capable of flexible radial expansion, in such a way that, upon the ascending face of the outer sleeve being pressed against the ascending face at the inner sleeve under the action of the clamping means, the sealing ring is thrust out radially.
