Abstract: An enclosure for retaining an electrical connection between a receptacle from a first electrical cord and a plug from a second electrical cord comprises a lower shell hingedly attached to the upper shell and a latch for securing the upper and lower shells into a closed position. In a first embodiment, an inside surface of one or both of the shells may include an elongated protrusion extending into the enclosure interior space for deformably engaging lateral surfaces of the receptacle and plug, thereby creating a frictional force to resist connection separation. The enclosure may also include protrusions or sectional annuli for engaging the first and second cords for resisting cord movement during the application of tensile loads on the electrical connection. Finally, the enclosure may also include a sheath fixed to the receptacle or plug.
