Quick connect tubing connector and method of assembly

A method of assembling a tube unit for insertion within a housing, comprising the steps of:

• (1) forming an outer radially greater portion on a tube at an axial location spaced from a first axial end of said tube;
• (2) placing a locking member on said tube between said outer radially greater portion and said first end;
• (3) placing a sleeve on said tube between said locking member and said first end, such that said locking member is secured on said tube between said outer radially greater portion and an outer axial extent of said sleeve;
• (4) forming an inner radially greater portion between said sleeve and said first end to secure said sleeve on said tube;
• (5) forming a seal retaining portion in said tube between said inner radially greater portion and said first end of said tube;
• and
• (6) placing a seal on said seal retaining portion.

A fluid connector comprising:

• a housing defining a bore, said bore extending axially inwardly into said housing from an entrance portion, a radial face being defined in said bore axially inwardly of said entrance portion;
• a tube received within said bore, said tube having a first upset portion of relatively large diameter;
• a sleeve surrounding said tube axially outwardly of said first upset portion, an axially inner end of said sleeve contacting said first upset portion to retain said tube in said bore;
• a retainer surrounding said tube axially outwardly of said sleeve, an axially inner end of said retainer contacting an axially outer end of said sleeve to retain said sleeve in said bore, said retainer having arms extending away from said axially inner end of said retainer and contacting said radial face to retain said retainer in said bore;
• and
• a second upset portion formed on said tube axially outwardly of said axially inner end of said retainer, said second upset portion securing said sleeve and said retainer on said tube.
