The invention concerns an injection device comprising a syringe body (1, 13) defining a chamber designed to be filled with a liquid, and a member (17) for dispensing the liquid comprising an end bit (17a) sealing the chamber extended by a locking tapered male connection (17c) capable of axially moving between a position sealing said chamber and a position for injecting the liquid. The invention is characterised in that the dispensing member (17) comprises an intermediate section (20) arranged between the sealing end bit (17a) and the tapered male connection (17c). Moreover, the syringe body (1, 13) comprises a ring (3) defining two superposed compartments with forms matching the intermediate section (20) of the dispensing member (17), separated by a neck (9) capable of allowing said intermediate section to be axially displaced, and comprising a collar (12) extending in the upper compartment (8) extension so as to house said sealing member tapered male connection (17c).
L'invention concerne un dispositif d'injection comprenant un corps de seringue (1, 13) délimitant une chambre destinée à être remplie d'un liquide, et un organe (17) de distribution du liquide comportant un embout (17a) d'obturation de la chambre prolongé d'un raccord conique mâle (17c) à verrouillage, et apte à se déplacer axialement entre une position d'obturation de ladite chambre et une position d'injection du liquide. Selon l'invention, l'organe de distribution (17) comprend un tronçon intermédiaire (20) ménagé entre l'embout d'obturation (17a) et le raccord conique mâle (17c). De plus, le corps de seringue (1, 13) comprend une bague (3), d'une part, délimitant deux compartiments superposés de formes conjuguées du tronçon intermédiaire (20) de l'organe de distribution (17), séparés par un col (9) apte à autoriser un déplacement axial dudit tronçon intermédiaire, et d'autre part, comportant un collier (12) s'étendant dans le prolongement du compartiment supérieur (8) de façon à loger le raccord conique mâle (17c) dudit organe d'obturation.
