ABSTRACT:
The specification discloses an article of furniture, specifically a chair base, in which the open sockets at the ends of the base arms are capped by a cap including a cover portion and a plug portion extending into the arm socket, the plug extending over and beyond the top of the pintle socket which is inside the leg and including a barb extending downwardly behind a portion of the pintle socket, the barb being sufficiently flexible as to allow it to slide over the pintle socket and slip down behind at least a portion of it whereby insertion of the cap is facilitated but removal is not. The plug also includes inclined locking ridges which engage the interior surface of the socket to further secure the cap in place.
