Did you ever see those funny outlets (usually in hallways) that have three prongs arranged in a circle? Those are "twist-and-lock" socket for special plugs. When you plug them in to the wall, you twist them, locking them in place and preventing accidental disconnects. A quick call to a local electrician or good hardware store should get your client what they need.
