The present invention relates to electrical cords and more specifically to electric cord connectors for various uses, including holiday lighting, that allows Christmas light strings to be installed with either end of the cord connectors at the power source. A connector can include a receiving port for a corresponding connector. Both male and female connectors of the present invention, can be manufactured on the electric cords or can include individual replacement type connectors or adaptable replacement connectors. Cords with just a first and second female connector are coupled together and the aligned contact slots are linked with a linking male fitting. An adapter cord powers up the these cords with an activating male fitting. The improved cords, used for holiday lighting, such as Christmas, also includes an improved Christmas light socket with clip, wherein the light socket is one half of the clip and an elongated body member is the other half, resulting in an improved clip with less parts that can be broken.
