This receptacle is provided with other openings 13 .for re-.

ceivlng clips 14 of conventional construction for carrying the circuit current. With this device may be used a plug such as shown at 15 having prongs 16 insertable in openings 13 and a prong 17 insertable in the opening 12 to en age the clip 10. Prongs 16 and clips 14 w' carry the circuit current inthe usual well known manner while the features of construction, and in the elevation of a plugused 1927. Serial No. 180,897.
