Abstract: A weatherproof safety case for a plug and receptacle connection of electrical power cords. The case includes a molded plastic housing divided into first and second parts having mating edges. An integrally molded hinge of thin plastic material joins the first and second parts along one side of the mating edges. A clasp-like member extends alongside one of the mating edges. The resilient gasket is formed with an enlarged pad adjacent to each end of the hinge for providing a seal between the hinge and the mating edges when the case is shut. The case also includes labyrinth seals, each labyrinth seal being divided into two portions by the mating edges of the first and second parts of the housing Each portion is coupled to either the first or second part of the housing, and is formed with at least two spaced apart flexible partitions having semicircular edge cutouts. One of the edge cutouts is of a larger diameter than the other.
