Abstract
Improvements are disclosed to known twist-lock electrical connectors, whose plug blades form parallel segments of a common cylindrical form. After insertion in a compatible receptacle, rotating the connectors relative to each other engages features intended to prevent accidental separation, but which do not positively lock. An improved plug is disclosed providing positive locking and with prior art receptacles.
