Patent ID: 7467813

Claim:
A fluid coupling assembly comprising: a connector body defining an axially extending tube receiving bore including an axial cylindrical surface defining an entrance opening, a retainer axially insertable into said bore of said connector body through said entrance opening, said retainer including a body portion disposed within said bore, and four spaced apart locking members extending rearward from said body portion toward said entrance opening, capable of radially inward deflection on insertion of said retainer through said entrance opening, said locking members each including a rear abutment surface and a front abutment surface disposed radially inward of said rear abutment surface, said locking members each defining at least one radially outward facing deflection surface engageable with said axial cylindrical surface defining said entrance opening during insertion of said retainer into said bore, said at least one deflection surface on at least one of said locking members being disposed axially forward, toward said retainer body portion, of said deflection surfaces on at least two other of said locking members and engageable with said axial cylindrical surface defining said entrance opening prior to engagement of said axial cylindrical surface defining said entrance opening prior to engagement of said axial cylindrical surface defining said entrance opening by said at least one deflection surface on said at least two other of said locking members.
