Abstract: A self-locking connector system has a connector member having an external thread and an axially extending keyway, and a connecting interface at a distal end. A connector body has a distal end with a connecting interface that mates with the connecting interface of the connector member. An internally threaded nut is captive on the distal end of the connector body encircling the connecting interface and is configured to screw onto the externally threaded connector member. A locking collar is dimensioned to encircle the externally threaded connector member, has at least one key dimensioned to engage in the keyway, and is movable axially on the nut between a first position in which the nut is rotatable relative to the collar and a second position in which the nut is not rotatable relative to the collar.

Abstract: A connection device comprises first and second connectors. The first connector has a sleeve having axially extending slots at a distal end to define tines yieldable resiliently inward, and a resilient seal encircling the sleeve proximally of the slots. The second connector has a shroud dimensioned to receive the distal end of the first connector sleeve within the shroud and to engage the first connector resilient seal when the sleeve is fully received within the shroud.
