PURPOSE:To constitute a cartridge which can be easily attached and detached to and from a vessel and can be thereby exchanged by providing a fluid introducing port which is communicated with the fluid treating part of the vessel via the fluid inflow port of the vessel mounting part and a fluid discharging port communicated with this treating part via a vessel outflow port to the mounting part of a connector. CONSTITUTION:The cartridge 1 for fluid treatment is moved downward relative to the connector 2 for the cartridge and is then turned to fit and connect the mounting part 21 of the connector 2 integrally to the vessel mounting part 17 of the cartridge 1. A fluid introducing pipe 18 of the vessel mounting part 17 is inserted into the fluid introducing port 22 of the mounting part 21 at this time; in addition, the fluid discharging port 23 of the mounting part 21 is inserted into the annular recess between the projecting part of the pipe 18 and the annular fitting outside pipe part of the mounting part 17, by which the fluid introducing port 22 and fluid discharging port 23 of the connector 2 are communicated with the fluid treating part 14 of the vessel 11. The fluid introducing port 22 and the fluid discharging port 22 are concentrically formed and the mounting part 21 is formed as double pipes.
