A fastener device ( 4, 5 ) for fastening a fluid dispenser member ( 2 ), such as a pump or a valve, on a neck ( 11 ) of a fluid reservoir ( 1 ), said device comprising: a fastener ring ( 4 ) including both a reception housing ( 47 ) that is suitable for receiving, in stationary manner, the dispenser member ( 2 ), and fastener means ( 42 ) for holding the ring ( 4 ) on the reservoir ( 1 ), the fastener means ( 42 ) being formed at a bushing ( 41 ) that can be locally deformed radially outwards while the ring is being mounted on the reservoir; and a covering ferrule ( 5 ) that surrounds, at least in part, the bushing ( 41 ) of the fastener ring ( 4 ), the ferrule being at a distance from the bushing ( 41 ) at the fastener means ( 42 ), so as to form a free intermediate gap (E) making it possible to deform the bushing ( 41 ) radially outwards; the device being characterized in that the ferrule ( 5 ) is engaged with a wall ( 412 ) of the ring ( 4 ) that is directed radially inwards. |
