A filling device for cartridges with an annular outlet opening (20) inside a cartridge neck (14), in the center of which there is a fixed center element (18), includes a valve cap (34) that is shiftable disposed on the neck (14) which, in a first position into which valve cap (34) is pretensioned, covers over annular outlet opening (20) by means of an inwardly projecting annular flange (38) and, in a second position, uncovers outlet opening (20). The filling device includes: PA1 a cylindrical filling nozzle (12) with a concentric feed bore (52) for filling material inside, PA1 a sealing sleeve (46) that encloses filling nozzle (12) concentrically and can be displaced longitudinally in relation to the filling nozzle, PA1 claws (40) on an end portion of filling nozzle (12) destined to come into contact with the cartridges, which grip valve cap (34) and move it into the open position as a result of the filling nozzle (12) being pulled back, and PA1 a drive assembly for independently displacing the filling nozzle (12) and/or sealing sleeve (46) longitudinally.
