A functional component of a fluid filter is provided with at least one component connection element of a mechanical connection device, wherein the at least one component connection element can be connected releasably to at least one corresponding housing connection element of the mechanical connection device by a rotation/push-in movement about a virtual axis. The at least one corresponding housing connection element is provided at a filter housing of the fluid filter. The at least one component connection element has at least one securing contour that interacts with at least one joining element to secure the mechanical connection device and prevent an accidental release of the mechanical connection device, wherein the at least one joining element is connected to the filter housing after the functional component has been mounted at the filter housing.

A fuel filter comprises a filter screen, a heating element, and a coating. The filter screen includes a first hollow member. The heating element is disposed within the first hollow member. The coating is formed of a thermally conductive, electrically insulating ceramic in a hydrodynamic filtering pattern surrounding the filter screen but having a different shape than a shape of the hollow member.
