A connecting clamp is described which is adapted for easily releasable attachment to a bar or tube having a multi-cornered cross-section. The clamp consists of a yoke having fixed jaws at its ends. One jaw fits closely to one corner of the bar or tube, and the other jaw extends past an opposite corner of the bar or tube and at an obtuse angle, so that a tapering interspace is formed. A wedge for securing the clamp is pressed into said space by a bolt attached to the midpoint of the wedge and extending through the yoke. A recess in the obtuse-angled jaws allows the bolt to swing aside when the wedge has been retracted past the tip of the jaw, thus clearing the tapering space and enabling the removal of the clamp. |
