Abstract: 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.

Abstract: A collet assembly for telescoping pole structures and the like including inner and outer collet members. The inner collet member is mounted upon a first pole and includes a plurality of integral flexible fingers. The inner collet member is staked to the pole by deforming small sections thereof into spaces between the flexible fingers. The outer collet member has a tapped interior threadedly engaging a tapped exterior portion of the inner collet member, which threaded portion is spaced inward from the free ends of the flexible fingers. An interior peripheral portion of the outer collet member is tapered to urge the fingers radially inwardly when the outer collet member is threaded onto the inner collet member. A collet ring is positioned within an annular recess collectively formed by recesses provided along the interior periphery of each of the fingers and is pressed against a second tube telescoped into the collet assembly when the outer collet member is tightened onto the inner collet member.
