A pair of assembling claws 11 are projected from both upper and lower end surfaces of the body 10. On the other hand, shoulders 21 project from both upper and lower ends of the cover 20, and assembly pieces 22 project from the rear edge of each shoulder 21 toward the body 10. Each assembly piece 22 has an assembly claw 11 provided on the body 10.
A pair of engaging holes 22a are formed to engage with the concave and convex portions. A guide surface 11a is formed at the front end of the assembly claw 11 such that the guide surface 11a is inclined so that the amount of protrusion from the body 10 decreases toward the front. Therefore, when assembling the cover 20 to the body 10, the assembly piece 22 bends along the guide surface 11a,
Finally, the engaging hole 22a provided in the assembly piece 22 is
The body 10 and the cover 20 are connected to each other. As described above, since the assembly piece 22 needs to be bent, the cover 20 is formed of an elastic synthetic resin.

If the other electric wire is used as a feed wiring for connecting to another outlet, a connection operation for connecting a plurality of outlets in parallel becomes easy. In addition, since the electric wire on the power supply side and the electric wire serving as the feed wiring are individually connected, they are connected to the outlets that should be disconnected without disconnecting the two electric wires at the same time when removing the already connected outlet. Since only the electric wires need to be replaced, it is possible to easily cope with a change in wiring.

On the front wall of the cover 20, there is formed one insertion portion 24 into which a pair of blades provided on one plug can be inserted. The insertion portion 24 is composed of two insertion ports 25 which are respectively opened at portions corresponding to the spring pieces 31 and 32 of each blade receiving member 30, and each insertion port 25 is a flat type into which a flat plug blade is inserted.
