The wall is provided with openings (4) and a filter sleeve (6) is positioned around the pipe (1). Said filter sleeve (6) is supported with respect to the pipe (1) by means of elongated members (5) which extend transversely with respect to the valleys and crests and which are connected, e.g. glued, adhered or welded to the crests (2). The filter sleeve (6) is supported on the outside of the elongated members (5).
