The invention relates to a closure device ( 100; 200; 300 ), for fitting to an opening ( 41 ) of a fluid product reservoir ( 4 ), said device being embodied in a monobloc form by injection/moulding of plastic material and comprising a fixing body ( 110; 210; 310 ) for cooperation with the opening on the reservoir to produce a sealed fixing, a distribution duct ( 120; 220; 320 ), forming an outlet passage ( 121; 221; 321 ) for the fluid product contained within the reservoir, said duct forming a distribution opening ( 122; 222; 322 ), a closing body ( 13; 23; 33 ), for sealing said duct, said closing body being connected to the distribution duct ( 120; 220; 320 ) by means of at least one link of material ( 132; 232; 332 ), designed to break on the first withdrawal of the closing body. The invention is characterised in that said closing body ( 130; 23; 33 ) comprises a sealing part ( 131; 231; 234; 331; 334 ), said sealing part, before sealing, leaves the distribution opening free and, after sealing, closes the distribution opening ( 122; 222; 322 ) in a sealed manner.
