<p>The raceway (2) has six modules (21-26) defining lateral walls provided with a lateral part and other lateral parts (61-66, 81, 83-86), respectively. Some of parts of the two adjacent modules are connected together by bands (812, 823, 834, 845, 856) deformed between flat and folded configurations. Each band is flat in extensions of the corresponding parts and maintains a distance (d8) between the parts with a value, in the flat configuration. The band is folded and maintains the distance between the parts with another value (L'812) lesser than the former value, in the folded configuration.</p> |
