The profiled-section segments consist of small bars (1, 2) having a lateral hole (3) of uniform cross section. These holes are juxtaposed and traversed by a train of elements (9, 10) having a central part with a cross section which is substantially equal to the cross section of the holes (3) and ends in the shape of a hook (11, 14) ensuring mutual catching of the elements together. The end small bars are fastened to the end elements of the train. The small bars have rounded sides (4, 5, 6, 7) in the shape of an arc of a circle which nest into one another. <IMAGE>
