In order to connect the edges of slabs, for example precast-concrete slabs, in different angular positions, the invention provides two mutually parallel rails (2, 3) which are drawn together by screws (4, 5). The rails (2, 3) are provided with bent-off portions (10, 11), only the free edges being intended to bear on the slabs (6, 7). The cavity (12) remaining in the interior between the two rails and the slabs permits variations in the adjustment angle of the slabs. The device is suitable for producing load-bearing members, partition walls, exhibition structures and the like. <IMAGE>
