Abstract: This invention is concerned with safety devices which prevent children from accessing electrical outlets. It is designed to be easy to install, easy to use, and most importantly, safe. It is designed to have a cover which replaces the standard outlet cover found on electrical outlets. Attached to the cover is a removable cover which slides into place and affirmatively locks. To disengage the device, some manual dexterity and strength is required. The locking mechanism must be pushed with a requisite degree of spring force to enable the cover to disengage. The pathway which the electrical cord follows to access the interior of the apparatus is curved and non-linear so that it cannot be easily probed with a foreign object.
