ABSTRACT:
A framework for use as a support at fairs and exhibitions comprises section ubes connected to other tubes by means of clamp elements. Each clamp element includes a mounting portion which is longitudinally received within a longitudinal inner space of a profile tube, and a clamping portion which is received within a longitudinal external groove of another tube. The inner space has recesses for receiving the mounting portion in different orientations. The recesses are arranged in sets whereby when the clamping element is in one set of recesses it is oriented in one manner, and when in another set of recesses it is oriented in a different manner.
