ABSTRACT:
Two separate but identically shaped sections cooperate to form an electrical cord gripping device when they are brought together. The sections are insertable into recesses in cooperating halves of an electrical housing, by wedging or snapping them into place, and, when the housing is closed, the sections form a restricted opening and provide a clamp around an electrical cord passing through the opening and into the housing. The sections are readily removable from the housing, so that a single housing can be used with electrical cords of different sizes. Further, each section contains a diagonal rib, and, when the sections are brought together, their ribs criss-cross one another to grip the cord from opposite sides. The sections are also shaped to provide abutting surfaces which overlap each other to cam the sheathing of the electrical cord into the opening provided by the sections, and prevent crimping of the sheathing.
