The dispensing device according to claim 1, wherein, each dispensing nozzle has a nozzle body adapted to dispense the product and an entry channel coupled to the nozzle body; and wherein the support plate comprises openings provided with a shoulder, the first and second dispensing nozzles being fitted into the openings, andthe first guide block being secured to the first dispensing nozzle by at least one fastening element; the first dispensing nozzle abutting against the shoulder of the support plate; the coupling being wedged between the first guide block, the first dispensing nozzle, and the support plate. 6. The dispensing device according to claim 5, wherein at least a portion of the first guide block rests against at least a portion of a base face of the coupling, the coupling comprising a channel having a first opening which opens onto the at least a portion of the base face, and wherein the dispensing device comprises at least one sealing device interposed between the coupling and the first guide block, and wherein at least one face among the faces of the guide block resting against the coupling and the base face, comprises a circular groove in which the sealing device is seated, the sealing device being compressed by the at least one fastening element. 7. The dispensing device according to claim 5, wherein the channel of the first guide block opens onto a contact face, which lies in a plane substantially parallel to the support plate, the dispensing device comprising two fastening elements fastening the first guide block to the first dispensing nozzle, and wherein the channel of the first guide block comprises a delivery path and a discharge path which open onto the guide hole, one on either side of the hole along a diagonal of the contact face, and wherein the two fastening elements are arranged one on either side of the guide hole, along a second diagonal of the contact face. 8. The dispensing device according to claim 1, wherein each plug comprises at least an upper portion, a groove for receiving a fastening wedge, and a lower portion separated from the upper portion by the groove, and wherein the diameter of the upper portion is less than or equal to the diameter of the lower portion. 9. The dispensing device according to claim 5, comprising a static sealing device arranged between the first guide block and the first dispensing nozzle. 10. The dispensing device according to claim 9, wherein the nozzle body comprises a central hole provided with an internal shoulder, the first guide block comprising a lower end face resting against the internal shoulder, and wherein at least one face among a face of the internal shoulder and the lower end face is provided with a groove, the static sealing device being seated in the groove. 11. The dispensing device according to claim 1, wherein the first guide block is identical to the second guide block. 12. The dispensing device according to claim 1, wherein the coupling comprises a passageway for fluid that is generally U-shaped. 13. The dispensing device according to claim 1, wherein the coupling is made of elastomer. 14.
