1. A dispenser for dispensing a fluid, the dispenser comprising a dispenser member, a container with a neck, and a fixing member for fixing the fluid dispenser member to the neck of the container, said fixing member comprising a skirt defining an inside wall, said inside wall being provided with at least two longitudinal ribs extending over the height of the skirt, said ribs co-operating by plastic deformation with an outside portion of the neck. 2. A fluid dispenser according to claim 1, in which the ribs define an inside diameter smaller than the outside diameter of the neck before the fixing member has been mounted on the neck so that the ribs are deformed plastically over an outside bearing surface of the neck after said fixing member has been mounted on said neck. 3. A fluid dispenser according to claim 1, in which the neck forms a reinforced portion of larger diameter and that projects outwards, the ribs co-operating with said reinforced portion. 4. A fluid dispenser according to claim 3, in which the ribs extend to below said reinforced portion. 5. A fluid dispenser according to claim 3, in which the reinforced portion is provided with at least one retaining notch into which the ribs penetrate by plastic deformation. 6. A fluid dispenser according to claim 5, in which said at least one notch extends around the periphery of the reinforced portion. 7. A fluid dispenser according to claim 5, in which said at least one notch extends over the height of the reinforced portion, said at lest one notch having a width smaller than the width of a rib so that the rib is held by plastic deformation in said notch. 8. A fluid dispenser according to claim 7, in which said at least one notch has a width that tapers from the top end of the neck. 9. A fluid dispenser according to claim 1, in which the fixing member further comprises a trim band which covers the skirt at least in part. 10. Fixing device for fixing a fluid product dispenser on a container neck, said device comprising a fixing ring defining a substantially cylindrical skirt having an outer wall, and an inner wall adapted to co-operate with an outer wall of the container neck, characterized in that the inner wall of the skirt is provided with longitudinal ribs extending through the height of the skirt, said ribs being adapted to engage the outer wall of the neck with a tight contact, the skirt comprises longitudinal inner recesses located radially outwardly of the ribs and extending in the thickness of the skirt, so that the ribs may be deformed radially outwardly in their respective recesses without deforming the outer wall of the skirt. 11. Fixing device according to claim 10, wherein the longitudinal recesses do not open on the outer wall of the skirt. 12. Fixing device according to claim 10, wherein the outer wall of the skirt is in contact with a trim band on its periphery. 13. Fixing device according to claim 10, wherein the recesses are larger than the ribs. 14. Fixing device according to claim 10, wherein the recesses are open at a lower end of the skirt and are formed as blind holes extending axially in the thickness of the skirt from its lower end between said outer and inner walls.
