Abstract
A spray or injection device that includes a casing or a pusher that includes at least one tab configured to move radially between a first radial position in which the tab does not impede the movement of the pusher with respect to the casing, and a second radial position in which the tab opposes movement of the pusher. The tab includes an opening. The pusher or the casing, respectively, includes at least one ramp-shaped projection configured to bring the tab into the second radial position then to penetrate the opening thereby allowing the tab to return to the first radial position. The pusher or the casing, respectively, further includes at least one stop region against which the tab abuts when the tab is brought into the second radial position by the projection. The stop region occurring just before the projection being opposite the opening.
