Abstract
A flexible tube (1) has mutually parallel ring-shaped flutes, end connectors (2) and longitudinal support cables (4, 5, 102) which hold said connectors against changes in axial spacing, and are rigidly joined to the connectors in the direction of pull and/or pressure, and against which the tube is at least indirectly braced. The longitudinal cables are held on the tube by rings (104) that ensure the radial relative position between tube (1) and cables (4, 5, 102) and hold the cables while the tube (1) is guided along these rings via the cables. The rings are formed by two ring segments, each of which has a hole (109) at the respective segment end to retain the cables therein.
