Abstract

The invention relates to the civil engineering and may be used for fast detachable joint of tubular elements, for example, posts and bearers in scaffolding construction. Summary of the invention consists in the fact that in the tubular joint, including a pair of adjoint tubular elements, the diameter of the tubular element on the jointing sector at one of its ends is smaller than the inner diameter of the other end by the value of the calculated clearance. On the external surface of this jointing sector there is made, at least, one rib, containing longitudinal and sloping sectors. On the other end of the tubular element, from inside thereof, there are executed prominences, the number of which correspond to the number of the ribs, and the dimensions and the shape correspond to the cross section of the ribs. The technical result consists in increasing the strength of the tubular elements jointing sector and the reliability of the tubular joint. Claims: 1 Fig.: 4
