Abstract
A connector for providing a fluid tight connection to a fluid port having internal threads. The connector includes an exterior sleeve having a split collet retractably mounted therein. The split collet defines an axial bore and includes a distal end portion extending axially outward from an end of the sleeve and adapted for lockingly engaging the threads of the fluid port. A sealing structure is mounted on the distal portion of the collet for providing a fluid tight seal with an end portion of the fluid port. The connector further includes an expansion pin mounted within the axial bore of the split collet adjacent to the distal end portion of the split collet. The expansion pin cooperates with the split collet to move the split collet radially inward and outward. A cross member connects the expansion pin to the exterior sleeve for preventing relative axial movement between the exterior sleeve and the expansion pin. The cross member is preferably aligned generally transversely with respect to the longitudinal axis of the sleeve.
