Abstract

An improved connector for removably interconnecting elongate structural members, comprising a sleeve member adapted to be removably fitted to an end of the structural member and holding an internally threaded nut apparatus, a connector bolt one end of which is threaded in the nut apparatus and having a T-head at the other end, and a tapered cylindrical collar having a concentric bore, through which the bolt extends. The T-head is adapted to non-rotatably engage an appropriately sized aperture. Intermediate the collar and sleeve, and located about the bolt, is a bias spring which biases the collar towards the T-head to hold the bolt in engaging relation with the aperture in which the T-head is inserted. The connection between the aperture and bolt may be secured by rotating the nut apparatus in a predetermined direction. A hollow connector ball, having a plurality of apertures adapted to receive and be engaged by the T-head of the bolt, is also provided to allow the structural members to be interconnected at various angles.
