ABSTRACT:
An apparatus for securing an electrical male plug to a female receptacle includes a serrated edge on at least one pin of the plug that cooperates with a retaining member in the receptacle. Linear insertion of the plug into the receptacle allows a portion of the retaining member to engage with at least one sawtooth of the serrated edge sufficient to secure the plug thereto until the retaining member is urged from a first position into a second position, the second position being adapted for release of the retaining member from the serrated edge, at which time the plug can be linearly withdrawn from the receptacle. Fixed-in-position as well as portable extension cord use is described.
