摘要

A protective device for a quick connect coupling having selectively connectible male and female coupling bodies (B,C) includes a cylindrical releasing sleeve (142) which has an integral flange (210) extending axially beyond and radially outwardly of an end face of one of the male and female coupling bodies. The flange (210) has a radially outwardly tapering shape to add desired rigidity and bulk thereto. The protective device is designed to extend axially outward beyond either the female receiving member or the male stem portion in both a first outermost biased position and a second innermost position.
