Fuel filter cartridge for filtering and heating fuel for an internal combustion engine, comprising: - a pot-shaped housing, which has a housing casing running in circumferential direction, a housing base and a housing opening axially opposite the housing base, - a filter element inserted into the housing for filtering the fuel, which in the housing separates an untreated room from a clean room, - an electrical heating device arranged in the housing for heating the fuel, - a cover inserted into the housing for closing the housing opening, - an inlet connector for the fuel, which is connected fluidically to the untreated room, - an outlet connector for the fuel, which is fluidically connected to the clean room, - an electrical connector arranged on the cover for the electrical power supply of the heating device which is connected electroconductively to the heating device, characterised in that - fuel filter cartridge has a thrust ring made of metal which is separate from the housing and the cover, which thrust ring encompasses the electrical connector which is secured directly or indirectly onto the housing and which is supported axially on the cover directly and/or indirectly on an outside of the cover averted from the housing base, - for securing the thrust ring onto the housing a crimping ring is provided, which is crimped to an end face housing edge encompassing the housing opening and formed on the housing casing, - the crimping ring and the thrust ring are separate components, so that the thrust ring is secured indirectly via the crimping ring to the housing, - the crimping ring is supported axially on the thrust ring on an outer side of the thrust ring averted from the housing base. - a pot-shaped housing, which has a housing casing running in circumferential direction, a housing base and a housing opening axially opposite the housing base, - a filter element inserted into the housing for filtering the fuel, which in the housing separates an untreated room from a clean room, - an electrical heating device arranged in the housing for heating the fuel, - a cover inserted into the housing for closing the housing opening, - an inlet connector for the fuel, which is connected fluidically to the untreated room, - an outlet connector for the fuel, which is fluidically connected to the clean room, - an electrical connector arranged on the cover for the electrical power supply of the heating device which is connected electroconductively to the heating device, - fuel filter cartridge has a thrust ring made of metal which is separate from the housing and the cover, which thrust ring encompasses the electrical connector which is secured directly or indirectly onto the housing and which is supported axially on the cover directly and/or indirectly on an outside of the cover averted from the housing base, - for securing the thrust ring onto the housing a crimping ring is provided, which is crimped to an end face housing edge encompassing the housing opening and formed on the housing casing, - the crimping ring and the thrust ring are separate components, so that the thrust ring is secured indirectly via the crimping ring to the housing, - the crimping ring is supported axially on the thrust ring on an outer side of the thrust ring averted from the housing base.
