The element (2) has an engaging unit (18) provided on an upper side (14) of a floor panel (4) i.e. steel platform, where the upper side turns away from a collecting panel (10). The engaging unit projects the element on a lower side (16) of the floor panel for producing an engagement on the collecting panel. A mounting unit (22) is mounted on an outer wall (20) of the collecting panel, and turns away from the floor panel and on the engaging unit. The mounting unit limits an inlet opening (12) projected in direction of the floor panel, where the panels are formed by a foldable sheet plate (8). |
