Abstract
Abstract 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).

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
139 words
A cable duct comprising a bottom (1) and two side walls (2, 3) the top portions of which (6, 7) are bent inwards and, adjacent the transition between each side wall (2, 3) and its inwardly directed portion (6, 7), provided with snapping means (8) arranged to engage corresponding snapping means (10) at the longitudinal edges of a lid (9), characterized in that, at their free ends, said top portions (6, 7) have hook-like snapping means (11, 12), the snapping means (11) of the one top portion (7) being arranged alternatively to engage either the snapping means (12) of the other top portion (6) or the snapping means (8) at the opposite side wall (2), whereby the duct may alternatively be closed with a lid (9) or in either of two different snapping-engagement positions giving the duct reduced cross-sections.
