Abstract

A textile tube (1) made in an injection-blow molding process and/or an injection evacuation process has a wall (2) with a wave profile with ring-shaped surrounding inward bulges (3) and outward bulges (4) alternately arranged side by side in an axial direction. The textile tube (1) has perforations (5). In several places arranged offset in relation to each other in a circumferential direction, the textile tube (1) has several strip-shaped areas (7) of a rigidity that differs from the rigidity of radially adjacent areas of the textile tube, and the strip-shaped areas (7) substantially follow the shape of the casing of the textile tube. In the case of fastenable textile tubes, a coupling is provided with a coupling aperture enclosed by a flexible wall area (16) and a matching rigid end lip (15) with the wall section (18) adjoining the end lip (15) being of equally flexible construction.
