Abstract: An electrical plug locking assembly for preventing plugging a male electrical plug into an electrical outlet includes a block member of a first material and having a plurality of openings for receiving prongs of a male electrical plug. Arm portions of a second material are coupled to the block member. Further, a locking member is securable through the pair of arm portions extending from the block member. When secured to the arm portions, the lock member holds the arm portions in a position adjacent to a rear portion of a head of the male electrical plug when the prongs of the plug are inserted into the block member. Thus, the arms are held in a position preventing removal of the prongs from the block member.
