A thin wall, resilient, generally tubular shaped sheath is fitted over a conventional electrical outlet plug and extends the length of the plug prongs. The sheath forms a barrier wall around the prongs in the space between the plug body and the conventional wall-type receptacle into whose openings the prongs are normally inserted. The sheath resiliently collapses endwise when the plug prongs are inserted within the receptacle openings, and resiliently returns to its normal shape when the prongs are withdrawn. Consequently, the wall formed around the prongs by the sheath, at all times prevents child contact with partially exposed, electrically energized prong portions.
