First Claim
1. 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.

Abstract
A fluid coupling assembly comprising a connector body defining a bore extending axially forward from an entrance opening, a tubular male member with an upset, a seal member, and a retainer. The retainer is received within the bore and includes locking members to releaseably retain the tube. The retainer includes a forward extension to support the seal against fluid pressure. The retainer and seal are configured to be applied to the male member before insertion of the male member into the bore of the connector body. Two of the locking members include ramps extending radially outwardly to contact the body portion defining the entrance opening sequentially prior to contact by the locking arms of the other locking members.

6. A fluid coupling assembly comprising:
-
a connector body defining an axially extending tube receiving bore including a 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 at least two locking members extending rearward from said body portion toward said entrance opening, said at least two locking members being capable of radially inward deflection on insertion of said retainer though said entrance opening, said locking members each defining at least one deflection surface engageable with said surface defining said entrance opening during insertion of said retainer into said bore, said at least one deflection surface on one of said at least two locking members being disposed axially forward of said at least one deflection surface on another of said locking members of said at least two locking members toward said retainer body portion and engageable with said entrance opening defining surface nor to engagement of said entrance defining opening surface by said at least one deflection surface on said another of said at least two locking members, wherein said at least one locking member having said at least one deflection surface disposed axially forward of said at least one deflection surface on another of said at least two locking members includes at least one ramp defining said at least one deflection surface, and wherein said retainer body portion comprises an annular ring and, said locking members include at least one column extending axially rearward away from said annular ring and wherein said at least one ramp on said at least one locking member is disposed on said at least one column. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34)
