An electric socket is built into the wall of an electric furnace so that the cover can be pushed in or pulled out. The cover is spring-loaded and hinged so that it can be folded open through 90 degrees. The socket is made with a compartment with a locking lever pivoting about an axis against the action of a spring. It supports the hinge of a cover flap will lock when pressed down. The hinge has two guide pins engaging in recesses in the pocket. The socket is anchored behind the front wall by an intermediate wall. The cover flap is made with a cam section near the hinge so that it can be forced open with the thumb.
