ABSTRACT:
The retainer has a base plate lying between the dual sockets of an electric outlet. The base plate is mounted over the outlet shield and secured with the same screw which secures the shield. Paired flanges extend outwardly from the base plate and a pair of spaced spring legs with feet extend from each of the flanges at an angle. The legs lie parallel to the shield and the feet extend normally inwardly into spring pressed contact with the shield. A plug is inserted into a socket by manually flexing the feet and legs outwardly. Upon plug insertion and release of manual flexing, the legs spring back into engagement with the plug urging it toward inserted position with the feet out of contact with the shield. When one plug is inserted, the unused pair of legs and feet bear against the shield and off-set the levering-twisting at the base plate and screw and aid in exerting force against the inserted plug. When two plugs are inserted, one off-sets the other.
