A unique fluid connector is disclosed that quickly connects a tube within a housing bore, while providing a strong, fluid tight seal. The tube has axially spaced radially greater diameter upset portions with a sleeve and a locking member trapped between the upset portions. The locking member includes resilient arms which secure it within the housing bore. The sleeve has a notch at an inner axial end which abuts the inner upset portion to retain the tube within the bore. An O-ring is positioned axially inwardly of the upset portion. The sleeve and the inner upset portion both abut the O-ring to provide a fluid tight seal between the tube and the housing. In a unique method, a tube unit is assembled by forming the outer upset portion on the tube. The locking member and sleeve are then moved onto the tube. The inner upset portion is then formed on the tube to secure the locking member and the sleeve on the tube. An O-ring retaining portion is then formed on the tube, and the O-ring is positioned onto the tube. The assembled tube unit is then inserted into the housing bore. Further, a flexible tube may be connected to an outer end of said tube by crimping a metal ferrule radially inwardly.
