Each strip extends the full width of the insulating body and has a plurality of prongs I 4 which respectively extend through slots I6 in the insulating body. The prongs on the strip I3 are indicated at I4. The strip I 2 has a laterally extending portion I1 which is secured to the body I 0 by a screw I8 and outwardly from which there extends prong I9. Screws and 2| further secure the strip I2 in place upon the insulating body.
Also in the body I0 is a recess 22 in which may be disposed a fuse 23. A terminal clip 24 receives one end of the fuse 23. This terminal clip 24 is integral with a prong 25 aligned with the prong I9. 'Ihese prongs I9 and 25 enter the wall receptacle.
