Abstract: A tube (34) is characterized by having an end disposed in a socket member (12) and presenting a radially extending U-shaped projection (38) defined by legs (39) in mating engagement with one another, and presenting an enlarged end (40) extending radially outwardly with the projection (38) from the remainder of the tube (34) and spaced from the projection (38) to define a saddle between the enlarged end (40) and the projection (38) for receiving a seal (42). The enlarged end (40) of the tube (34) is seated against a tube seat (24) of the socket member (12) and the enlarged end (40) and the projection (38) fit snugly within the socket member (12).

Abstract: A quick disconnect member (36, 136) is retained on a tube (12) for sliding movement therealong to react with the projection (18) and includes a pair of arms (42) each with a V-shaped abutment (38) biased radially outwardly into a locked position in overlapping engagement with a shoulder (28) to prevent removal of the tube (12) from the socket. A resilient safety plug (44) is disposed between the tube (12) and the abutment (38) for preventing abutment (38) from disengaging from the shoulder (28). The safety plug (44) retains hooks (43) radially outwardly against the lip (32). The safety plug (44) presents an annular ridge (46) extending into the V-shaped abutment (38) to retain the safety plug (44) in the socket member (14) and a radially extending flange (48) abutting the distal ends of the arms (42).
