A novel fluid coupling and seal assembly. The assembly includes a coupling body 12 having generally concentric first and second bores 36,38 of greater and lesser diameters, respectively, the first bore also being provided with a generally cylindrical groove 44. A resilient retainer 14 is assembled within the generally cylindrical groove, the retainer having a plurality of prongs 52 which extend inwardly and towards the second groove. A seal assembly 16 is disposed within the coupling body between the retainer and the second bore, the seal assembly including an O-ring 60 formed of an elastomeric material and a tearable diaphragm 64 integral with and of the same material as the O-ring and capable of blocking the passage of fluid through the O-ring prior to the insertion of a fluid line 24. The fluid line which is adapted to be associated with the coupling is provided with a flange 26 which is engaged by the free ends 58 of the resilient prongs to hold the fluid line within the coupling assembly.

A seal assembly comprising an annular seal formed of a rubber-like material and a tearable diaphragm integral with and of the same material as the annular seal and capable of blocking the passage of fluid through the annular seal, the tearable diaphragm being provided with weakened portions which permit a central portion of the tearable diaphragm to tear when a tubular fluid line is inserted into the annular seal, the weakened portions not extending entirely about a central portion of the diaphragm whereby the central portion will be retained by the annular seal after tearing. A resilient retainer for use in a fluid coupling assembly to which a fluid line having an outwardly extending flange may be connected, said resilient retainer comprising: a generally cylindrically shaped radially compressible body portion which is C-shaped in cross section, said body portion being formed of resilient metal or the like, a plurality of prongs formed of the same material as the body portion, one end of each of the prongs being integral with the body portion, the prongs extending inwardly in the same direction at an acute angle to the adjacent surface of the body portion, and a plurality of skirt portions between the prongs, which skirt portions are coextensive extensions of the body portion, the skirt portions all being at least as long as the prongs.
