ABSTRACT:
A fluid connector and lock combination is described for connecting a tube to a base element. A relatively fixed, threaded base element has a passageway for passing fluid. A threaded mounting connector for surrounding the circumference of a portion of a tube is provided and which also mounts the tube to the relatively fixed, threaded base element through threaded engagement. The connector maintains a seal between the tube and a corresponding surface in the base element when the connector is sufficiently threaded to a sealed position relative to the base element to prevent leakage of fluid across the seal. A linkage is provided between the connector and the base element for preventing unthreading of the connector from the sealed position relative to the base element. The linkage includes a first portion which is linked to the connector and a second portion which engages slidingly in an axial direction the base element for preventing relative rotation between the connector and the base element.
