ABSTRACT:
A lockable electrical socket has a pair of grasping jaws which can retain an electrical plug in place. The plug can be released by pushing in the plug and then allowing the plug retaining assembly and the plug to be thrust out under spring pressure. In a second embodiment a key is required to thrust out the plug in order to prevent unauthorized removal of the plug from the socket. A dummy or safety plug can be used in place of an electrical plug to make the lockable socket child-proof.
