Tubular fence

A fence construction kit comprising, a plurality of individual tubular posts, a plurality of tubular cross-pieces each of generally uniform cross-section along its entire length and all having alike first and second ends, means defining apertures in the posts for receiving the ends of cross-pieces extending therein and for supporting the ends of the cross-pieces on the posts when the posts are upstanding and with the cross-pieces disposed transverse to the posts while allowing a relative movement of the cross-pieces and posts along an axial direction of the cross-pieces, said posts having upstanding tabs adjacent the periphery of said apertures, means defining in an end portion of each of the cross-pieces a plurality of recesses spaced-apart from one another along an axial direction of the cross-piece, said recesses of each end of a cross-piece being receptive of said tabs to selectively and releasably position cross-pieces axially relative to a post in any one of a plurality of discrete axial positions defined by said recesses, and locking means cooperative with the posts and the ends of the cross-pieces for releasably securing the cross-pieces in any one of said discrete axial positions relative to the posts.
