The connectors consist of three elements which are stacked one on the other on a common axis with the face of each element which abuts that of another including recessed formations which between the opposite element faces define sockets for trapping the headed ends of space frame members with the axes of the sockets between a first pair of element faces lying in a common plane and those between the second pair of faces being inclined relatively to and on the same side of the plane containing the axes of the sockets between the first pair of element faces and means for clamping the elements in the direction of their common axis. | |
