The invention relates to cable ducts and solves the problem of making it possible alternatively to close a given duct either with a lid (9) or by snapping engagement between portions (6, 7) directed inwardly from the top portions of the side walls (2, 3) of the duct. The snapping means (8, 11, 12) are shaped and located in such a way that they may alternatively cooperate either mutually (8, 11, 12) or with a lid (9, 10). |
