Abstract: An arrangement (1, 2) of a coupling (3) and a double-walled tube or hose (4). The double-walled tube or hose (4) includes two coaxially arranged sheaths (5, 6). The coupling (3) includes: a first, inner sleeve (14), surrounding an inner fluid conduit (7) for transfer of a first fluid, wherein the inner fluid conduit (7) is configured to fluidly connect with the fluid conduit (7) formed by the first, inner sheath (14) of the flexible tube or hose (4); a second sleeve (15), surrounding the first, inner sleeve (14); a third sleeve (16), surrounding the second sleeve (15); and a fourth, outer sleeve (17), surrounding the third sleeve (16). The first (14) and the second (15) sleeve form a receiving space (27) for receiving the first, inner sheath (5) of an end (13) of the double-walled flexible tube or hose (4); the third (16) and fourth (17) sleeve form a receiving space (28) for receiving an end (13) of a second, outer sheath (6) of the double-walled flexible tube or hose (4); and the second (15) and third (16) sleeve form an outer fluid conduit (23) for transfer of a second fluid, wherein the outer fluid conduit (23) is configured to fluidly connect with the fluid conduit formed by the clearance (8) between the first, inner (5) and the second, outer sheath (6) of the double-walled flexible tube or hose (4). The fluid connector part (19) of the inner fluid conduit (7) of the coupling (3) and the fluid connector part (25) of the outer fluid conduit (23) of the coupling (3) are displaced from each other in an axial direction of the coupling (3).
