The invention relates to a fluid product dispensing device comprising a pump (50) and a dispensing head. The dispensing head consists of a body (1) and a product discharge channel (2) comprising a dispensing orifice (3) at the end thereof, a rigid insert (4) being disposed in said discharge channel (2). The aforementioned rigid insert forms, or is solidly connected to, the delivery valve (54) of the pump (50). Moreover, the dispensing head comprises a plugging element (10) which is disposed in the discharge channel (2) and which can move and/or be deformed between a sealing position in which the discharge channel (2) is blocked and a non-sealing position in which the discharge channel (2) is not blocked. Furthermore, the rigid insert (4) can move in the discharge channel (2) between a rest position and an operating position. The inventive device is characterised in that the plugging element (10) co-operates with (i) the rigid insert (4) and (ii) the dispensing orifice (3) such that, in the insert (4) rest position, the plugging element (10) is in the sealing position and hermetically seals the dispensing orifice (3) and, in the insert (4) operating position, the plugging element (10) is moved and/or deformed axially towards the non-sealing position.
