Abstract
A spiral band (400) having a lock arm (420) for resisting rotation of a coupling nut (300) relative to a plug shell (100), coupling nut (300) including a radial flange (322) having a plurality of detents (340) disposed equiangularly therearound and spiral band (400) being tightly spiraled to interference fit an annular groove (110) of plug connector shell (100) and dome shaped to axially bias the plug shell (100) oppositely of the coupling nut (300), radial expansion of the spring band (400) relative to the plug shell by lock arm (420) allowing uncoupling rotation and radial contraction of spring band (400) followed by lateral deflection of the lock arm from engagement with the detent (340) allowing uncoupling rotation.
