Abstract: Elements for a modular system for the assembling of furniture, containers, partitions or the like, that consists of polygonal panels and bracing elements for a flat or spatial connection of single panels. Each of the panel elements (10) has several cut-out sections (12) in its borders (11). In each of the cut-out sections (12) there is inserted a rod (13) running essentially in the same direction as the border. Each of the bracing elements has the shape of a clamp (20) which can be inserted into the cut-out sections of adjoining panel elements (10) and whose rods (13) are shaped for gripping, preferably to establish a drop-in connection (FIG. 1).
