Abstract

The present invention relates to a disposable cartridge. A housing (70) forms a cartridge (22), and a slider (72) is displaceably provided in the housing (70) with a set of guide rails (78) in between. A hook (80) is tiltably provided between the guide rails (78). After the cartridge (22) is installed in a piercing device (10), the slider (72) is displaced to the other end side of the housing (70) while in contact with a casing (12) forming the piercing device (10). This causes the hook (80) not to be tiltable by the slider (70). An end of the hook (80) comes into contact with a step (26) of the casing (12) to limit the installation of the cartridge (22) in the piercing device (10).
