A quick-connect coupling for non-rotatably connecting a hose to a male stem member is made of plastic and includes a plastic fitting body on which is mounted a plastic annular cap having depending lugs. The cap is welded or otherwise fixed to the end of the fitting body. A plastic collet is slid into the annular cap.
