Abstract

A quick connector coupling has either a linear or an angled female coupling member, a male coupling member which is attached to a radiator, a bushing, a sealing means, and a locking ring, which maintains the connection of the male coupling member and the female coupling member. The male member has at least one chamfered surface, which is complementary to a chamfered surface on the bushing element. The locking ring is disposed around the female coupling member and has a plurality of indentations which pass through apertures positioned around the collar end of the female member. These indentations interconnect with an annular groove around the male member when coupled to the female member, securing the connection.
