Abstract: A connector mate/demate tool provides remote coupling and decoupling of connector sections with a rotating locking ring on one section of the connector and where the other section is rigidly attached to some fixture. The tool mates the connector sections by first searching for a key-slot engagement of parts while exerting a small longitudinal force and then rotating the locking ring until the two sections are secured. Demating is accomplished by rotating the locking ring in the reverse direction and pulling the two connector sections apart.
