A clamp for connecting two elements, arranged at an angle to each other, in a support structure, consists of a first jaw and a second jaw hinged to each other at a respective first ends by joint means designed to enable the jaws to be attached to an internal portion of a head of a first element. The opposing jaw ends projecting from the head are shaped to form a clamp for coupling with corresponding retaining seats on the second element. A spreading screw acts on the jaws to move the jaws apart away from each other so that the jaws press on the retaining seats thereby forming a connection between the two elements.
