Cartridge for setting devices

A cartridge for a setting device, comprising a pot-shaped plastics material cartridge housing (2, 10), which has an outer surface (8) for contact with an inner surface (12) of a cartridge chamber of the setting device, said cartridge having an open end and a closed end and an open end-closed end direction and a sealing cover (3) for closing off said open end (4) of the housing (2, 10), said sealing cover (3) has a cylindrical section (6), extending into an interior (5) of the housing (2, 10) with an outer surface thereof in surface contact with an inner surface of said housing (2, 10), said cylindrical section (6) has an outside diameter (d) wherein the housing (2, 10), in a region of the surface (8), has a section extending in the open end-closed end direction and at least in part enclosing and in contact with said cylindrical section (6), at least one recess (7) formed between said outer surface (8) and the cartridge chamber at a distance (a) spaced in the open end-closed end direction from the open end (4) of the housing and extending at least partially in a radial projection region of the cylindrical section (6), said recess (7) being continuous in the open end-closed end direction and the recess (7) extending in the open end-closed end direction and is an open space outwardly from the outer surface (8) of the housing (2, 10) to the inner surface (12) of the cartridge chamber so that upon ignition of said cartridge a section of said cylindrical section (6) and of said housing (2, 10) spaced by the distance (a) from the open end (4) is expanded radially outwardly into positive locking action between the housing (2, 10) and the sealing cover (3) in at least a partial section of said cylindrical section (6) extending in the open end-closed end direction with said inner surface (12) in the open end-closed direction of said recess (7).
