The invention claimed is 1. An inhalation aid for use in connection with an aerosol dispenser, said inhalation aid comprising a chamber having an opening at one end for connection to an aerosol dispenser and a mouthpiece opening at an opposite end of the chamber for drawing aerosol from the aerosol dispenser at the one end, said chamber having a variable volume and delimited or surrounded by a conically tapering expansion bellows made of a continuous, elastic material, the expansion bellows including at least one ring-shaped reinforcement having a material cross section increased relative to adjacent portions of the expansion bellows, a housing at the other end of the chamber, said housing including the mouthpiece opening, and a retaining ring removably connecting the housing to the expansion bellows at the other end of the chamber, the expansion bellows, in a folded state, being received in the housing, the retaining ring being connectable and detachably connectable with the housing provided to receive the expansion bellows. 2. The inhalation aid according to claim 1, wherein the expansion bellows is made of silicone. 3. The inhalation aid according to claim 1, wherein an outer surface of the expansion bellows is stepped or offset in a region of end faces of the at least one ring-shaped reinforcement oriented towards a tapering end. 4. The inhalation aid according to claim 1, wherein the expansion bellows has a reduced material cross section in a portion immediately following the at least one ring-shaped reinforcement, on a chamber side face oriented towards an interior of the expansion bellows. 5. The inhalation aid according to claim 1, wherein the expansion bellows, on the other end of the chamber has a bead or flange to which the retaining ring is fixable. 6. The inhalation aid according to claim 1, wherein the connection between the retaining ring and the housing is a screw connection or bayonet catch. 7. The inhalation aid according to claim 1, wherein a cover is provided for the openings of the chamber. 8. The inhalation aid according to claim 1, wherein the at least one ring-shaped reinforcement is of substantially constant diameter. 9. An inhalation aid for use in connection with an aerosol dispenser, said inhalation aid comprising a chamber having an opening at one end for connection to an aerosol dispenser and a mouthpiece opening at an opposite end of the chamber for drawing aerosol from the aerosol dispenser at the one end, said chamber having a variable volume and delimited or surrounded by a conically tapering expansion bellows made of a continuous, elastic material, the expansion bellows including at least one ring-shaped reinforcement having a material cross section increased relative to adjacent portions of the expansion bellows, a housing at the other end of the chamber, said housing including the mouthpiece opening, a retaining ring removably connecting the housing to the expansion bellows at the other end of the chamber, the expansion bellows, in a folded state, being received in the housing, and markings, or snap-on or adjusting elements being provided on at least one of the retaining ring and the housing. 10. The inhalation aid according to claim 9, wherein the expansion bellows is made of silicone. 11. The inhalation aid according to claim 9, wherein an outer surface of the expansion bellows is stepped or offset in a region of end faces of the at least one ring-shaped reinforcement oriented towards a tapering end. 12. The inhalation aid according to claim 9, wherein the expansion bellows has a reduced material cross section in a portion immediately following the at least one ring-shaped reinforcement, on a chamber side face oriented towards an interior of the expansion bellows. 13. The inhalation aid according to claim 9, wherein the expansion bellows, on the other end of the chamber has a bead or flange to which the retaining ring is fixable. 14. The inhalation aid according to claim 9, wherein a cover is provided for the openings of the chamber. 15. The inhalation aid according to claim 9, wherein the at least one ring-shaped reinforcement is of substantially constant diameter.
