Abstract
A lockable electrical cord connector unit having a cylindrical connector housing made of electrically non-conductive material. A locking control ring telescopes over the connector housing and it is mechanically connected to structure within the connector housing that allows male electrical connector members extending from the housing to be locked into a female electrical socket. In an alternative embodiment the connector housing may have female sockets that can lock onto a male electrical terminal by using the same locking control ring structure. A second alternative embodiment provides for the connector housing to be an adaptor having male electrical terminal prongs extending from one end and having a female electrical socket formed in its other end. The locking ring allows both ends to be locked to mating electrical terminals.
