PURPOSE: A connection element of a supporting frame is provided to connect six cross beams respectively for easily forming various structure like cubic frames and/or slant racks, thereby simplifying the assembling. CONSTITUTION: A connection element(10) of a supporting frame includes a basic unit(12) and one or more connection units(11). Each of the connection unit is formed in the L-shape and has grooves(113) formed at both ends mounted with elastic plates(112), the elastic plates being folded inwardly, so that ends of cross beams are coupled with the connection units. The basic unit has an opening at a side to be sealed by a door(13) and side surface plates(121) at the other side for forming a complete cubic hollow unit. A side surface plate(111) of each connection units has two holes(115), and the door and the side surface plates of the basic unit have five holes(132,122).
