A flexible conduit pipe for transporting fluids is specified, which consists of two corrugated metallic tubes, an inner tube (1) and an outer tube (2), which are arranged concentrically to one another and are separated from one another by an encircling annular space in which a spacing means is arranged. The spacing means consists of a plurality of rings (4,5) which bear with a basic body (6) against inner tube (1) and outer tube (2) and are arranged at an axial distance from one another in the annular space (3). The rings (4,5) have on their inner circumferential surface a rib (7) which extends in the circumferential direction, corresponds to the corrugation of the inner tube (1) and engages in a respective corrugation trough of the inner tube (1). At least three projections (8) are provided at least on one part of the rings (4) on their basic body (6), which projections (8) are offset from one another in the circumferential direction, protrude radially outwards and engage in the corrugation of the outer tube (2).
