Abstract: Device for blocking a fluid product reservoir with a neck, having a cap, a fixing ring to hold the cap on the neck, the fixing ring having a cylindrical structure with wall parts separated by lateral windows, each wall part having at least one inner radial projection to hold the cap in the fixing ring, each lateral window having a lower edge provided with at least one rigid lug extending radially inwards from the lower edge. The rigid lugs, in the blocking position of the fixing ring, are arranged under a neck of the reservoir, to thus fix the fixing ring on the reservoir. A blocking cover is provided having a cylindrical wall and an upper wall and arranged around the fixing ring to lock said fixing ring in its blocking position. The upper surface of the cap has a deformation profile that engages, after assembly, with the fixing ring.

In the stored position the inner body closes the dispenser orifice of the needle and the outer body co-operates with the injection device to fasten the protection device on the injection device. The protection device includes a protection system against accidental pricking, having protective flaps that are integral part of the outer body and movable between a covering position in which they cover the needle, and an open position in which the needle is uncovered. The protection system has a control ring that slides over the outer body so as to move the flaps from their covering position to their open position, before injection, and from their open position to their covering position, after injection.
