A fluid dispenser device having a body (10), a reservoir (20), a dispenser head (100) and a dispenser member (30) mounted on the reservoir by a fastener ring (60). Also provided is a lateral actuator system (40) including an actuator element (41) movable between a rest position and an actuated position. The body (10) includes a guide surface (50) that is stationary relative to the head and substantially parallel to the central axis of the dispenser member (30). The actuator element (41) co-operates with the guide surface (50). The guide surface (50) includes a resistance element (55) that modifies the co-operation between the actuator element (41) and the guide surface (50). In order to be passed over, the resistance element (55) require the user to act on the lateral actuator system (40) with an actuation force that is different.
