1. A de-icing device of an aircraft gas-turbine engine with an engine cowling enclosing at least one inflow region, with the engine cowling having a double-walled design, comprising: at least one annular tube element extending in a circumferential direction and including outlet openings for passing hot air to an inflow region of the gas turbine engine, in order to de-ice the inflow region;a plurality of fastening elements mounting the tube element to the engine cowling in the circumferential direction;each fastening element including two struts, each strut including a first end area for mounting to the engine cowling and a second end area connected to the tube element, wherein the two first end areas are spaced apart from one another in the circumferential direction along a central axis of the tube element, and the two second end areas are connected to each other, such that the two struts form an angle to each other with respect to the central axis of the tube element; each fastening element thereby providing relative movability of the tube element with respect to the engine cowling. 2. The de-icing device in accordance with claim 1, wherein the first end areas are provided on a circular path which is arranged concentrically to the central axis of the tube element. 3. The de-icing device in accordance with claim 2, and further comprising a carrier element connecting the second end areas to each other and to the tube element. 4. The de-icing device in accordance with claim 3, wherein the tube element is elastically connected to the carrier element. 5. The de-icing device in accordance with claim 4, wherein the carrier element is arranged in a plane vertical to the central axis of the tube element. 6. The de-icing device in accordance with claim 5, wherein the two struts are in a form of flat sheet-metal strips. 7. The de-icing device in accordance with claim 3, wherein the tube element is fixedly connected to the carrier element. 8. The de-icing device in accordance with claim 3, wherein the two struts provide a cantilever mounting of each fastening element with respect to the engine cowling. 9. The de-icing device in accordance with claim 2, wherein the two struts provide a cantilever mounting of each fastening element with respect to the engine cowling. 10. The de-icing device in accordance with claim 7, wherein the carrier element is arranged in a plane vertical to the central axis of the tube element. 11. The de-icing device in accordance with claim 10, wherein the two struts are elastically bendable. 12. The de-icing device in accordance with claim 1, and further comprising a carrier element connecting the second end areas to each other and to the tube element. 13. The de-icing device in accordance with claim 12, wherein the tube element is fixedly connected to the carrier element. 14. The de-icing device in accordance with claim 13, wherein the carrier element is arranged in a plane vertical to the central axis of the tube element. 15. The de-icing device in accordance with claim 14, wherein the two struts are elastically bendable. 16. The de-icing device in accordance with claim 12, wherein the tube element is elastically connected to the carrier element. 17. The de-icing device in accordance with claim 16, wherein the carrier element is arranged in a plane vertical to the central axis of the tube element. 18. The de-icing device in accordance with claim 17, wherein the two struts are in a form of flat sheet-metal strips. 19. The de-icing device in accordance with claim 1, wherein the two struts are elastically bendable. 20. The de-icing device in accordance with claim 1, wherein the two struts provide a cantilever mounting of each fastening element with respect to the engine cowling.
