The invention discloses a connecting device for a replaceable filter, an adapter of the connecting device, and a filter system with the connecting device. The connecting device includes a body which is used for a connecting line of a fluid; the connecting line is provided with at least one fluid opening. The connecting device is provided with an annular coaxial adapter, which has a radial annularsection which is extended in circumferential and at least radial directions. The radial annular section is at least partly axially arranged between the filter and at least one body at a connecting side of the connecting device. The radial annular section includes the adapter-axial sealing surface which is closed to an axial sealing portion; the adapter is provided with at least one axial annular section which is at least extended in the circumferential and radial directions, wherein the axial annular section is connected to the at least one radial annular section. The radial annular section isprovided with an adapter-
