<p>The strip (1) has front and rear walls (2, 3) defining a space inside the strip, where the walls are in a from of distinct metallic sections integrated at a level of their longitudinal edges (6, 7) along a direction transversal to the strip by locking sections (12, 13) that are made of insulating material i.e. synthetic material. The metallic sections have blocking units at the level of their edges, where the units are co-operated across complementary blocking units associated to the sections (12, 13) to ensure longitudinal axial immobilization of the metallic sections.</p> |
