ABSTRACT:
A quick-release connector wherein a tubular male component has a rear portion insertable into the end portion of a first conduit and a front portion insertable into the resilient front part of a tubular female component. The male component has an annular protuberance between the front and rear portions and the protuberance has a conical front flank and a radial rear flank. The rear part of the female component is insertable into the end portion of a second conduit and the front part has two arms with internal male detents within a ring which connects the front ends of the arms to each other. In order to insert the front portion of the male component, the conical flank of the protuberance is caused to move the detents apart until the detents snap behind the radial flank of the protuberance. An annular disengaging member has two parallel walls which are inwardly adjacent the arms behind the detents and have ramps which can be moved against the arms to thus move the detents apart and permit extraction of the protuberance and front portion of the male component from the female component. The disengaging member is more or less permanently connected with the female component and is movable transversely of the female component between a first end position in which the ramps deform the arms and a second end position in which the detents are free to engage the radial flank of the protuberance.
