Abstract
Abstract A strain relief element for electrical supply wires for use with small electrical appliance fixtures. The strain relief element is in the shape of a wedge which is inserted from the outside of the fixture through a wire-way opening. When the wedge is in place, it compresses the supply wires to the inner fixture wall and permanently locks itself to the fixture body.
