Abstract (en)
The tube (1) has a guiding tube (3) with an outer cladding surface (15) and an inner cladding surface (13), where the outer cladding surface surrounds an axis of the tube. Reinforcements (17) are designed in the form of knots and/or ribs (19) at the cladding surfaces of the guiding tube. The knots or ribs project outwards at the external cladding surface, where parts of the knots or ribs are arranged at a distance from front side ends of the guiding tube at a middle zone.
