Abstract
A tamper-resistant outlet cover uses a spreadable grounding socket engageable post to secure the cover in place to thereby block access to an electrical receptacle, typically a wall outlet. The post is spread by insertion of a spreader, typically a threaded screw. The head of the screw is configured to only be engaged by a cooperatively shaped tool. Installation and removal of the cover is thus afforded only to one in possession of the tool.
