Abstract
Abstract A receptacle is affixable to an end of an electric cord. The receptacle has a housing in which the end of the electric cord is inserted. The housing has a hinged cover which may be pressed to a closed position to place cutting contacts in electrical contact with the conductors of the electric cord. The cutting contacts extend from contact strips which are electrically connectible to female plug ferrules. The ferrules accommodate terminal prongs of a utensil. The plug ferrules may be of equal diameter for use with non-polarized utensils. The diameter of one of the ferrules may be larger than the other for use with polarized utensils.
