(57) An electrical connector particularly of the insulation displacement type. It comprises an electrically insulated main body, provided with a connector arm slidably mounted through the body to project from the body at either end. The connector arm has a pair of accessible holes for receiving a wire pair to be shorted in the connector to complete an electrical circuit. An electrically conductive element defining a pair of opposed slits aligned to be in the path of travel of the wire receiving holes, are mounted in the body, the conductive element forming a passageway in which the connector arm slides. Acutation of the connector arm moves the wire pair through the slit which is dimensioned to sever the wire insulation and short the wire pair through the metallic plates. To release the wire pair the connector arm is moved in the opposite direction and the connector is then reusable.
