The invention concerns a fluid product dispensing device, comprising a dispensing orifice (5), a reservoir (10) containing at least one dose of fluid product, at least one piston (15) sliding axially in said reservoir (10) for dispensing the fluid product, a dispensing member (20) co-operating with said piston (15), and an actuating element (30) co-operating with said dispensing member (20). The invention is characterized in that said dispensing member (20) is mobile between a locking position preventing said actuating element (30) from being actuated, and a releasing position, wherein the actuation of said actuating element (30) moves said dispensing member (20) to dispense a dose of fluid product, said dispensing member (20) being manually moved from its locking position to its releasing position prior to the actuation of said device.
