ABSTRACT:
The present invention is directed toward an electrical connection device that positively engages the plug and receptacle ends of electrical devices to extension cords, adjacent extension cords, or positively engages an electrical cord with a power receptacle. The invention is formed so that either the receptacle or plug end of an extension cord or the cover of an electrical outlet has at least one flexible finger, depending on its front surface. The extension cord end or the electric appliance plug engaging the flexible finger has an orifice on its face shaped to accept the flexible finger. As the plug and receptacle ends are pushed together, the flexible finger enters the face orifice. The flexible finger has a locking tab formed as part of its tip. As the flexible finger advances within the opposing face orifice, the locking tab eventually comes into contact with a side orifice. The locking tab, encouraged by the bias of the flexible finger, enters the side orifice. The interference of the side orifices edges against the locking tabe and prevents the flexible finger from withdrawing from the face orifice, thus positively engaging the plug and receptacle. The receptacle and plug are disengaged by deforming the locking tab below the side orifice and pulling the flexible finger from the face of the orifice.
