ABSTRACT:
A quick connect coupling including male and female elements that are adapted to fit axially in each other and each includes a valve that is displaced to an open position by engagement by a fixed pusher part of each element when they are being fitted together. The female element is provided with a locking member in which a part of the male element is received and which is reciprocally movable in a radial direction with respect to an axis of fit of the elements between two positions in which the locking member respectively allows or opposes the separation of the male and female elements and wherein the engaging surfaces of the valves and pusher parts is such that no open volumes or voids are created therein in which a liquid may collect during assembly or disassembly of the male and female elements.
