Abstract: One or more hoses (10) belong to the ventilation system which through a perforation are constructed at least partially as ventilation hose (60). Each of the hoses is permanently connected with a number of holding devices distributed over its length, which hold the hose (10) from below. The holding devices run in a guide rail (14). The hose (10) is drawn into the empty or liquid-filled basin (10) with a traction device along the guide rail (14) which introduces the tractive force onto the body of the hose and holds it there without prestress.
