1. A nasal breathing mask comprising: a mask part; a mask-holding part adapted to receive at least one strap for positioning the mask part on a nose of a user; a tube extending in an axial direction and having a first end connected to a top end of the mask-holding part and a second end, the tube defining an external surface; a breathing hose having a hose connection attached to the tube second end; a forehead-plate mount having an internal surface complementary with the tube external surface to create a positive engagement between the forehead-plate mount and the tube, wherein the positive engagement is releasable to allow adjustment of the forehead-plate mount in the axial direction; and a forehead plate connected to the forehead-plate mount. 2. The nasal breathing mask of claim 1, in which a side of the forehead-plate mount remote from the user includes a substantially U-shaped collar having an open end extending away from the user, an inside of the collar having recesses extending parallel to one another in the axial direction and annularly in a circumferential direction to define the internal surface, and in which the tube external surface is formed with annular ribs sized for releasable insertion into the recesses. 3. The nasal breathing mask of claim 2, in which the collar has an internal diameter that is slightly smaller than an external diameter of the tube, so that the forehead-plate mount is releasably latchable onto the tube. 4. The nasal breathing mask of claim 2, in which the recesses and ribs are arranged equidistantly in the axial direction. 5. The nasal breathing mask of claim 2, further comprising a latching clip adapted to releasably latch onto a side of the forehead-plate mount remote from the user. 6. The nasal breathing mask of claim 5, in which the latching clip includes two prestressed limbs, an end of each limb having a lug, and in which the forehead plate includes openings sized to receive the lugs such that the prestressed limbs releasably latch the lugs behind the openings. 7. The nasal breathing mask of claim 6, in which a side of the latching clip facing the user includes ribs adapted for insertion into spaces formed between adjacent ribs of the tube. 8. The nasal breathing mask of claim 5, in which an outside of the collar is formed with guides sized to receive the limbs of the latching clip. 9. The nasal breathing mask of claim 1, in which the tube includes an axially extending rib and the forehead-plate mount includes an axially extending groove sized to receive the axially extending tube rib. 10. The nasal breathing mask of claim 1, in which the forehead-plate mount is formed integrally with the forehead plate. 11. The nasal breathing mask of claim 1, in which the tube includes a flexible region positioned between the mask-holding part and the forehead-plate mount so that the mask part is movable toward the user with respect to the forehead-plate mount. 12. The nasal breathing mask of claim 11, in which the flexible region of the tube includes at least one ball joint or bellows. 13. The nasal breathing mask of claim 11, in which a flexurally elastic hose is provided between the mask-holding part and the tube. 14. The nasal breathing mask of claim 13, in which the mask-holding part includes a tube connection piece over which the flexurally elastic hose is pushed to form a seal. 15. The nasal breathing mask of claim 14, in which a distance over which the flexurally elastic hose extends between the tube connection piece and the tube is approximately 2 mm. 16. The nasal breathing mask of claim 1, in which the mask part and forehead plate are formed of silicone. 17. The nasal breathing mask of claim 1, in which the positive engagement is a latching/clamping connection.
