What is claimed is: 1. A foam dispenser, comprising: a housing; a fluid reservoir configured for placement in the housing and including an opening; a plug connected to the fluid reservoir in communication with the opening so as to permit fluid within the fluid reservoir to be withdrawn from the fluid reservoir; a foam pump including: an air pump; a fluid pump; a closable supply to the air pump; a nozzle; and a movable operating part, wherein the foam pump is configured to dispense a quantity of foam through the nozzle upon actuation of the operating part in a direction of pumping; and a coupling piece including a first side for connection to the foam pump and a second side for connection to the plug to combine the fluid reservoir, the plug, and the foam pump into a storage holder, the coupling piece being configured to removably and rigidly fasten the foam pump of the storage holder to the housing. 2. The foam dispenser according to claim 1, wherein: the housing is provided with an adapter in which the coupling piece is received; and the coupling piece and the adapter are provided with one or more elements for fixing and positioning the foam pump relative to the housing. 3. The foam dispenser according to claim 2, wherein: the adapter is provided with a resilient element that is supported by the coupling piece and with one or more latches that restrain the coupling piece in the adapter under tension. 4. The foam dispenser according to claim 1, wherein the housing is provided with a handle mechanically contacting the operating part of the foam pump for transferring a force in the direction of pumping. 5. The foam dispenser according to claim 4, wherein the handle is coupled to the operating part and the foam dispenser is further provided with a resilient element supported by the housing and exerting a force opposed to the direction of pumping on the handle. 6. The foam dispenser according to claim 4, wherein a maximum displacement of the handle in the direction of pumping or a maximum force transferable to the operating part can be set. 7. The foam dispenser according to claim 4, wherein the nozzle is part of the operating part and the handle is provided with an alignment element for aligning the nozzle. 8. The foam dispenser according to claim 1, wherein the closable supply forms a connection between a space outside the fluid reservoir and the air pump. 9. A storage holder configured for placement in a foam dispenser, comprising: a fluid reservoir having an opening; a plug connected to the fluid reservoir in communication with the opening so as to permit fluid within the fluid reservoir to be withdrawn from the fluid reservoir; and a foam pump, including: an air pump; a fluid pump; a closable supply to the air pump; a nozzle; and a movable operating part, wherein the foam pump dispenses a quantity of foam through the nozzle upon actuation of the operating part in a direction of pumping; and a coupling piece removably connected to both the foam pump and the plug, and configured to fasten the foam pump to a housing within which the reservoir can be placed. 10. The storage holder according to claim 9, wherein the fluid reservoir has a flexible wall to which the foam pump is connected in a substantially airtight manner. 11. The storage holder according to claim 9, further comprising: a surrounding housing with a rigid wall, suitable for suspension in a housing of the foam dispenser, wherein the wall of the surrounding housing comprises a detachable part for running the foam pump therethrough. 12. The storage holder according to claim 9, wherein the coupling piece comprises a threaded neck and the foam pump comprises a matching thread with which the foam pump is attached to the coupling piece. 13. The storage holder according to claim 9, wherein the foam pump has an air passage, of which one end is located in an outer wall of the foam pump facing the fluid reservoir, wherein the coupling piece is adapted to close off the air passage. 14. The storage holder according to claim 9, wherein the coupling piece is adapted to connect at least two parts of the foam pump to each other. 15. The foam dispenser according to claim 1, wherein the coupling piece enables use of a plurality of different foam pump configurations and a plurality of different fluid reservoir configurations with the housing. 16. The foam dispenser according to claim 1, wherein the foam pump and the coupling piece are configured to be removably secured to one another. 17. The foam dispenser according to claim 16, wherein the coupling piece includes a threaded male member for mating with and engaging threads on a complementarily configured female member of the foam pump. 18. A coupling assembly, comprising: a coupling piece for establishing communication between a foam pump and a reservoir for containing material to be dispensed by the foam pump, the coupling piece including: a pump coupling element configured to removably connect to the pump; a housing engagement element; a reservoir coupling element for connecting to the reservoir; and a passage extending through the pump coupling element, the housing engagement element, and the reservoir coupling element to enable material from the reservoir to be drawn through out of the reservoir; and an adapter configured to be rigidly associated with a housing of a fluid dispenser, the adapter including: a coupling piece engagement element for receiving and removably coupling to the housing engagement element of the coupling piece. 19. The coupling assembly of claim 18, wherein the pump coupling element includes a threaded element for engaging a complementarily threaded element of the pump. 20. The coupling assembly of claim 18, wherein the coupling piece engagement element includes a recess for receiving the housing engagement element of the coupling piece and at least one retention element for holding the housing engagement element of the coupling piece within the recess.
