A fastener device for closing a fluid reservoir (1) that is formed with a neck (10) that is provided with outer peripheral reinforcement (11) that co-operates with the remainder of the neck to define a bottom shoulder (12), said fastener device comprising: a fastener ring (2) for holding a closure member (4) on the neck (10), the fastener ring (2) including a peripheral skirt (21) that extends around the neck to below the bottom shoulder (12), said skirt (21) being provided with fastener elements (26a, 26b) that each form a contact zone (27a, 27b) that is suitable for potentially coming into engagement with the neck (10) below the bottom shoulder (12), so as to fasten the ring (2) on the neck (10); and a blocking hoop (3) that is engaged around the peripheral skirt (21) in a final mounted position, so as to block at least some of the fastener elements (26a, 26b) below the bottom shoulder (12); the fastener device being characterized in that the peripheral skirt (21) forms vertical blades (22) that are separated by axial slots (23), the blocking hoop (3) forming vertical branches (33) that are arranged in the axial slots (23) between two vertical blades (22), in the final mounted position. |
