ABSTRACT:
An improved fluid quick connect coupling includes a retainer and a lock ring. The lock ring locks the retainer legs against radially outward flexing. The lock ring is initially contacted by a tube being moved into the coupling, and moves with the tube, until it no longer prevents radially outward flexing of the retainer legs. The retainer legs then flex radially outwardly, allowing the tube to move to its fully inserted position. The lock ring is biased back outwardly once the tube is connected, and has tabs that extend axially outwardly beyond the retainer to provide a visual indication to the installer of when the tube is fully connected.
