This ring ( 3 ) is secured to the neck of a pouch ( 4 ) that has a deformable and flexible wall and contains the product to be dispensed, the pump body ( 2 ) bearing, above the clip-fastening collar ( 12 ), a seal ( 5 ) accommodated in an annular groove ( 6 ) in the pump body. At least the stop rib or the clip-fastening collar ( 8, 12 ) is provided with at least one vent hole ( 11 ).
