Abstract
A coupling nut (300) constrains a lock ring (400) to be moved into biased abutment against forward facing flank (222) of external thread (220) on a receptacle shell (200) as a result of the coupling nut being rotated about a plug shell (100) to which it is mounted, the lock ring (400) including a plurality of deflectable leaf spring fingers (406) adapted to engage said forwardly facing flank (222), uncoupling being resisted by a cam section of forwardly facing flank (222) being required to deflect leaf spring finger (406) downwardly and overcoming oppositely biased friction between rearward facing flanks (224, 324) tightened by coupling nut (300) when at the full mate position.
