Abstract
A quick-connect coupling for non-rotatably connecting a hose to a male stem member is made of plastic and in accordance with a first embodiment 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 collet is slid into the annular cap. The collet has depending arms which nest between the lugs on the annular cap so that the collet does not rotate. Detents on the arms seat in a groove on the male stem member to retain the stem member within the fitting body. In accordance with a second embodiment, the fitting body is in the form of a unitary female member which utilizes a substantially C-shaped resilient detent inserted radially through a slot in the female member to retain the male stem member therein by seating in a circumferential groove in the male stem member. The male stem member is made from hex-bar stock and is received in a hexagonal socket portion in the female member to prevent relative rotation of the members.
