Safety outlet

The device disclosed is an outlet which may be connected to a standard rubber insulated lamp cord without stripping the insulation and may be positioned at any point along the length of the cord. The cord piercing contacts are arranged to move with a clamp member which provides strain relief and which is so formed as to block the use of the outlet before the strain relief and the contacts are engaged and is further shaped to prevent the strain relief and the cord piercing contacts from being disengaged while a plug occupies the outlet.
