This is a model for assembling tubular profile sections, of different cross section, by means of: "openings" ("mouthfuls"), grooves, mortising and recesses therein. This means that there is no requirement for intermediate pieces, ribs, screws or welding for coupling them together. It is applicable industrially to the manufacture of modular structures for the production of furniture and for use in architecture (construction and restoration of buildings, ships, umbrella roofs, etc.). The advantages arising from the use of the present system are a saving of time, materials and work in the production and use of the abovementioned useables, together with easy recovery of the materials employed. <IMAGE>
