System for concealing an attachment of a duct (5) to and against a mainly perpendicular wall (4), comprising a cover frame (1) arranged to wholly or partly enclose the duct (5) on the wall (4), whereby the cover frame (1) consists of a wall collar (2.1), intended to extend along the wall (4), and a duct collar (2.2), intended to extend along the duct (5). The wall collar (2.1) and the respective duct collar (2.2) are manufactured from a spring material and show a cross section, which, on assembly of the cover frame (1), is deformed elastically by an external force which is directed against the cover frame (1) during attachment to the wall (4). The duct collar (2.2) exerts a directed spring force against the duct (5) by the springing back of the cover frame (1) after this external force has receded, by which means the cover frame is retained against the wall (4). One or more friction elements (3) can be arranged between the duct (5) and the duct collar (2.2). |
