A connector includes a shell and a coupling mechanism rotatably coupled thereto. The coupling mechanism includes an inner coupling nut and an outer coupling nut separate from the inner coupling nut. The inner coupling nut has internal threads configured to be threadably coupled to a mating connector. The inner coupling nut has a plurality of ramped steps disposed at different circumferential positions along the rear. The outer coupling nut has a detent successively engaging the ramped steps as the outer coupling nut is rotated in a tightening direction. The detent is released from the corresponding ramped step when the connector is fully mated to the mating connector. The detent engages a corresponding ramped step as the outer coupling nut is rotated in an untightening direction causing the inner coupling nut to rotate in the untightening direction.
