ABSTRACT:
A coupling for intercoupling at least two orthogonal bars or tubes includes an annular member surrounding one of the bars and rigidly fastened thereto. A loose annular member is also positioned on the bar and cooperates with angled guide surfaces. The other bars are provided with links having recesses and projections which cooperate with recesses and projections of the annular members. The rotation of the loose annular member results in it locking the links to the bar, by the cooperation of the loose annular member and the guide surfaces.
