US Patent 8177195 Connector components and methods of use

Interlocking clips are provided to assemble structures without the need for conventional fasteners. Structures such as fences, which may be assembled in situ, include the cooperating clips designed to provide a controlled amount of “play” between the pickets and rails of the fence to enable adjustment when racking the fences to accommodate sloping terrain. The clips are provided to interlock rails to cross members. The clips are preferably formed of a single sheet of a springy metallic material. The clips may be advantageously used to couple other types of apparatus.
