ABSTRACT:
In a plug-and-socket coupling, particularly between a spout of a portable liquid gas container and a regulator mounted thereon, in which the first coupling part has a discharge outlet adapted to receive a stud or protrusion of the second coupling part, leakage to the surroundings from a pressure fluid passage through the coupling is impeded by an annular gasket movably disposed within an annular chamber between the stud and a surrounding skirt. Between the gasket and the stud there is a passge for pressure fluid to the annular chamber behind the gasket for loading the gasket to closely but against the internal surface of the skirt and a surface on the first coupling part.
