ABSTRACT:
A pivotable pull ring is permanently attached to a low profile electrical plug by fashioning a locking stub at the attaching ends of the pull ring. Matching lock stub cavities in the electrical plug have "one-way" locking tabs which accept the locking stubs into the locking cavity during assembly, but which block the removal of the locking stub from the locking stub cavity once the locking stub is assembled into the locking stub cavity. The locking tab has a gentle ramp on the outside, to facilitate displacement of the locking tab to allow entry of the locking stub during assembly, but has an abrupt shoulder on the inside to prevent displacement of the locking tab after assembly.
