Abstract
A high pressure quick connector having a tube which includes an upset adjacent one end. A male locking assembly is positioned about the tube and includes a cavity enclosing the upset and a contoured outer surface defining first and second grooves spaced axially along the male locking assembly. A female member having an internal bore is adapted to receive the male locking member. The female member has an internal bore that includes a locking groove. An expandable annular locking ring is mounted about the contoured outer surface and the locking ring is initially mounted in the first groove and is slidable from the first groove to the second groove upon axial movement of the male locking assembly into the female member. The second groove is adjacent the locking groove upon full insertion of the male locking member into the female locking member with the expandable annular locking ring being positioned within the second groove and adjacent the locking groove so that the locking ring is nested between the adjacent second groove and the locking groove.
