ABSTRACT:
An electrical outlet safety cover includes an apertured base plate to replace the conventional face plate of an electrical outlet and is attached to such outlet at the original screw position. A box-like cover with openings for passage of an electric cord is provided for attachment to the base plate so as to enclose a cord attached to the outlet. The cord passes over a stop bar on the base plate in registration with the openings in the cover so that access to the outlet through the openings as, for example, by a child's finger or a tool is prevented. The cover and base plate include complementary locking members that coact when the cover is introduced to the base plate to effectively lock the cover to the base plate in a position where the locking members are completely enclosed by the cover and inaccessible from outside the cover so that the cover cannot be removed by manual manipulation. The locking member on the cover is constructed and adapted for movement in response to the presence of a magnetic force provided from outside of the cover to release it from engagement with the base plate and permit removal of the cover.
