Patent ID: 7699356

Claim:
A quick connector coupling having a primary use for connecting a fluid conduit to a radiator or heat exchanger housing, comprising: a male coupling member having a first end and a second end, wherein said first end attaches to a radiator housing and said male coupling member having at least one chamfered surface on the exterior of said male coupling member positioned between said first end and said second end, and said male coupling member further comprising an annular groove located around the outside of said male coupling member between said first end and said chamfered surface; a female coupling member, said female coupling member having a first inner bore at a first end, a second intermediate bore having an internal diameter smaller than said first inner bore, and a transitional bore, said transitional bore having an internal diameter less than said second intermediate bore, and a greater diameter than a bore of a second end of said female coupling member, said second end being opposite said first end and comprising a plurality of radial barbed flanges on the exterior of said second end; a bushing, said bushing having at least one interiorly chamfered surface, complementary to the at least one chamfered surface of said male member, wherein said bushing is positioned within said first inner bore, adjacent to said intermediate bore and wherein said bushing comprises an annular ridge which is received within a groove within said first inner bore of said female coupling member; a sealing means, said sealing means being circumferentially complementary to and positioned within said second intermediate bore, adjacent to said transitional bore and retained in position by said bushing; and a locking ring, said locking ring being generally C-shaped, having two distal ends and three evenly spaced indentations, one proximal each of said two distal ends and one centered between the two indentations proximal the distal ends, wherein said three evenly spaced indentations protrude toward a center of said first inner bore at said first end of said female coupling member and wherein said locking ring maintains the connection of the male coupling member and the female coupling member, by means of said female coupling member further comprising three slots positioned through the body of said female coupling member through said first inner bore for receiving the three indentations respectively of said locking ring when said locking ring is positioned around the outside of said female coupling member proximal said first end, said indentations engaging with said annular grove in a releasable, spring-lock connection means in said groove located around the outside of said male coupling member.
