Patent ID: 6905151

Claim:
A quick connect coupling selectively connecting two pipes, said coupling comprising; a male element of a size to be received within a female element along a principal axis of the coupling, a first locking element including at least one ramp for receiving a second locking element in a form of a radial projection extending from said male element for locking said male and female elements when they are connected by application of an axial force being applied to said male and female elements relative to said principal axis, said ramp being in a ring mounted inside said female element and having an inlet opening for entrance of said radial projection, and with an exit opening for exit of said radial projection, said openings being oriented at an angle with respect to said principal axis in two distinct radial directions, said ring being free to rotate about and fixed in translation along said principal axis, said second locking element being fixed with respect to said male element, and said ramp forming at least one seat for locking said radial projection when said male element is connected within said female element to permit fluid flow therethrough and whereby no rotation of said female element relative to said male element is necessary to lock said female element to said male element.
