1. A device for releasing breathing gas, the device comprising: an outer part;an inner part having a cylindrical sliding surface extending in an axial direction of said inner part; andan annular connection element with a mounting sleeve receiving said cylindrical sliding surface of said inner part to define a rotational sliding connection of said inner part to said annular connection element, said annular connection element having an annular stop fixing said inner part, said stop defining an inner part removal stop means for preventing axial removal of said inner part relative to said stop said, said annular stop extending in said axial direction, connection element and said outer part together forming a discharge gap between said connection element and said outer part. 2. A device in accordance with claim 1, wherein said outer part and said annular connection element cooperate to provide locking means for locking said annular connection element in said outer part. 3. A device in accordance with claim 2, wherein said locking means comprises spacing elements at an outer surface of said annular connection element. 4. A device in accordance with claim 3, wherein said spacing elements have snap-in pins at the outer surface of said annular connection element, said locking means further comprising grooves on an inner surface of said outer part, said grooves comprising locking grooves, wherein said snap-in pins snap into said locking grooves, whereby said inner part is nondetachably connected to said outer part. 5. A device in accordance with claim 1, wherein said inner part has a guide segment, which is connected via webs to an area of said sliding surface. 6. A device in accordance with claim 5, wherein said outer part has a contact surface corresponding to said guide segment. 7. A mount device for releasing breathing gas from a supply having a flexible tube to a breathing mask, the device comprising: an annular outer part with a mask port;an annular inner part having cylindrical sliding surface extending in an axial direction of said inner part and a flexible tube port; andan annular connection element with a mounting sleeve having a cooperating surface corresponding to said cylindrical sliding surface of said inner part for allowing rotational sliding of said inner part relative to said annular connection element, said annular connection element having an annular stop for fixing said inner part in an axial direction relative to said annular connection element and said outer part, said annular stop extending in an axial direction, and said annular connection element cooperating to provide locking means for locking said annular connection element in said outer part, said connection element and said outer part together forming a discharge gap between said connection element and said outer part. 8. A device in accordance with claim 7, wherein said discharge gap is formed by spacing elements between said annular connection element and said outer part. 9. A device in accordance with claim 8, wherein said spacing elements form part of said locking means and are positioned to fix said annular connection element in relation to said outer part in such a way that said annular connection element is secured against rotation. 10. A device in accordance with claim 8, wherein said spacing elements have snap-in pins that can be connected to said outer part. 11. A device in accordance with claim 7, wherein said inner part has a guide segment, which is connected via webs to an area of said sliding surface. 12. A device in accordance with claim 11, wherein said outer part has a contact surface corresponding to said guide segment. 13. A device in accordance with claim 7, wherein said locking means comprises spacing elements and snap-in pins at an outer surface of said annular connection element and grooves provided with locking grooves on an inner surface of said outer part, wherein said snap-in pins snap into said locking grooves whereby said inner part is nondetachably connected to said outer part and said discharge gap is formed between said annular connection element and said outer part. 14. A method of providing a mount device for releasing breathing gas from a supply having a flexible tube to a breathing mask, the method comprising the steps of: providing an annular outer part with a mask port;providing an annular inner part having a cylindrical sliding surface extending in an axial direction of said inner part, a shoulder and a flexible tube port;providing an annular connection element with a mounting sleeve having a surface receiving said cylindrical sliding surface of said inner part to define a rotational sliding connection of said inner part to said annular connection element, said annular connection element having an annular stop, said annular connection element cooperating with said outer part to provide locking means for locking said annular connection element in said outer part;inserting said inner part into said annular connection element such that said sliding surface is located within said mounting sleeve and said inner part is fixed, relative to said stop, in an axial direction via said stop said annular stop extends in said axial direction and;inserting said inner part together with said connection element into said outer part for locking said connection element to said outer part whereby said annular connection element and said outer part together form a discharge gap between said annular connection element and said outer part. 15. A method in accordance with claim 14, wherein said discharge gap is formed by spacing elements between said annular connection element and said outer part. 16. A method in accordance with claim 15, wherein said spacing elements form part of said locking means and are positioned to fix said annular connection element in relation to said outer part in such a way that said annular connection element is secured against rotation. 17. A method in accordance with claim 16, wherein said spacing elements have snap-in pins that can be connected to said outer part. 18. A method in accordance with claim 17, wherein said inner part has a guide segment, which is connected via webs to an area of said sliding surface. 19. A method in accordance with claim 18, wherein said outer part has a contact surface corresponding to said guide segment. 20. A method in accordance with claim 14, wherein said locking means comprises spacing elements and snap-in pins at an outer surface of said annular connection element and grooves provided with locking grooves on an inner surface of said outer part, wherein said snap-in pins snap into said locking grooves whereby said inner part is nondetachably connected to said outer part. 21. A device in accordance with claim 1, wherein said outer part and said stop cooperate to fix said inner part in an axial direction relative to said outer part and said annular connection element.
