Abstract: The disclosed invention improves upon electrical connectors that when mated together provide electrical continuity across the connectors, and that are held mated together by bayonet locking means. A sleeve element is threaded onto an exterior portion of one of the connectors and bottomed upon rotation against the opposite connector and/or support structure for the opposite connector. This bottomed sleeve element maintains the bayonet locking means engaged, and thereby prevents accidental disengagement of the connectors.
