An electrical connector includes a housing and a conductive contact member disposed in the housing. A first contact portion of the conductive contact member receives a blade contact of an electrical device and a second contact portion electrically engages an inserted electrical wire. A spring member is disposed in the housing and is connected to the contact member. A rotatable member is movable between first and second positions. When the rotatable member is in the second position the spring member secures an inserted wire in electrical engagement with the conductive contact member and prevents removal of the inserted wire. When the rotatable member is in the first position the spring member allows for removal of an inserted wire and allows for insertion of a wire in the housing.
