ABSTRACT:
A tube (34) for disposition in a socket member (12) is characterized by having an end disposed in a socket member (12) and presenting a radially extending projection (38) 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). The socket member (12) presents a radially extending shoulder and a quick connect member has an abutment (48) biased radially outwardly into a locked position in radial overlapping engagement with the shoulder to retain the tube (34) in the socket member (12) and moveable radially inwardly to a release position wherein the abutment (48) clears the shoulder to axially remove the quick connect member from the socket member (12) to remove the tube (34) from the socket member (12).
