Abstract
The joining piece has two semicircular recesses perpendicular to each other. A pivoted clamping arm, having the same semicircular recess, is fitted to each of the recesses in the joining piece. These clamping arms are held down on top of the tube by toggles which are clamped by a nut, an eccentric cam, or a sliding tapered bar. Positive axial location of the tubes can be obtained by using a tube with several groups of rectangular grooves on its periphery, combined with a rectangular ridge in the clamp recess. Plain tubing can be used with a plain semicircular recess.
