The hose has twisted ends held to one another about a longitudinal axis. Separate sealing elements (30) are arranged centrally in interior, and extend transversely to the longitudinal axis of the tube. Total length of the sealing elements is smaller than circumference of the tube. The sealing elements include a triangular cross section, and are slotted transversely to longitudinal direction. Height of the sealing elements is between 5 mm and 20 mm. The sealing elements are made of elastomer, natural and synthetic rubbers, silicone or closed cell ethylene-propylene-diene rubber material. |
