Abstract
The electrical plug guard comprises a disc member having a pair of elongated slots to frictionally receive the prongs of an electrical plug. The slots have centers offset with respect to each other along the length of the slots. The slots are effective to skew the prongs of the plug with respect to each other when the prongs are inserted in slots through the disc member. The disc member has a thickness sufficient to prevent finger contact with the prongs which are electrically active when partially inserted into an electrical plug outlet.
