description The present invention relates to a stopper (1) to be positioned inside a barrel (101) of an injection device (100), said stopper (1) comprising:- a gasket (10) comprising a through hole (71) extending from the proximal end to the distal end,- an insert (50) directly received in the through hole (71),wherein the stopper is adapted to deform between:a closed configuration wherein an outer surface (55) of the insert (50) sealingly engages the through hole (71) for preventing flow of the composition between the proximal end (11) and the distal end (12), a protruding portion (60) of the insert protrudes distally from the the gasket (10), andan open configuration wherein the protruding portion (60) of the insert abuts a distal end (104) of the barrel, and the outer surface (55) of the insert disengages from the through hole to open the fluidic pathway between the insert (50) and the barrel (101).
