The nasal assembly according to claim 1, wherein the nozzles are formed of silicone. 5. The nasal assembly according to claim 1, wherein the hollow body and nozzles are formed separately from one another and then attached to one another. 6. The nasal assembly according to claim 1, wherein each nozzle includes a cylindrical tube provided to the hollow body that supports the conical tip. 7. The nasal assembly according to claim 1, wherein the conical tip includes an outlet opening, the outlet opening having a circular shape. 8. The nasal assembly according to claim 7, wherein the outlet opening has an inside diameter of about 4 mm. 9. The nasal assembly according to claim 1, wherein the conical tip includes a widened portion having an outside diameter of about 10 mm. 10. The nasal assembly according to claim 1, wherein the hollow body has an inside diameter of about 6 mm. 11. The nasal assembly according to claim 1, wherein each end of the silicone cylindrical tube includes a cylindrical end portion, one of the end portions is provided with the plug and the other of the end portions is provided with the connector. 12. The nasal assembly according to claim 11, wherein positions of the plug and connector may be interchanged. 13. The nasal assembly according to claim 1, wherein the yokes are constructed from rigid or semi-rigid material. 14. The nasal assembly according to claim 1, wherein the yokes are constructed from polycarbonate. 15. The nasal assembly according to claim 1, wherein the yokes are at least partially covered with foam. 16. The nasal assembly according to claim 1, wherein each of the yokes makes an angle of about 120° with respect to a longitudinal axis of the hollow body. 17. The nasal assembly according to a claim 1, wherein each of the yokes includes a yoke ring for attachment to the hollow body. 18. The nasal assembly according to claim 17, wherein the yoke ring of one yoke is sandwiched between the plug and an end of the hollow body. 19. The nasal assembly according to claim 18, wherein the yoke ring of the other yoke is sandwiched between the connector and the other end of the hollow body. 20.
