Functional component of a fluid filter, and fluid filter

A functional component of a fluid filter comprising:

• a filter housing surrounding a virtual axis, comprising
• a housing pot;
• a housing cover arranged on and closing over an axial end face of the housing pot;
• a tubular fluid inlet arranged on an axial outer side of the housing cover;
• at least one mechanical connection device arranged on the axial outer side of the housing cover, the at least one mechanical connection device having:
• a first leg projecting axially outwardly away from the axial outer side of the housing cover;
• and
• a second leg arranged on an axial outer end of the first leg and projecting radially inwardly in a direction transverse to the first leg,
• wherein an axial spacing between the axial outer side of the housing cover and the second leg forms a bayonet receptacle;
• a heating device for heating a fluid, comprising:
• a component connection element having:
• a bayonet plate extending radially in a direction transverse to the virtual axis, the bayonet plate arranged at the axial outer side of the housing cover, the bayonet plate having:
• at least one bayonet nose arranged on and projecting radially outwardly away from an outer circumference of the bayonet plate, the at least one bayonet nose configured and positioned to be received into the bayonet receptacle by rotation of the heating device on the axial outer side of the housing cover into a mounting position, mounting the heating device releasably onto the filter housing,
• wherein the bayonet plate is rotatable on the axial outer side of the housing cover in a rotation direction about the virtual axis;
• wherein the heating device includes a concave depression extending radially inwardly and arranged at an axially outer side of the bayonet plate;
• a fluid conduit joining element pushed onto and received onto an axial outer end of the tubular fluid inlet, the fluid conduit joining element comprising:
• a radially outer securing contour configured to be received into the concave depression of the heating device is rotated into the mounting position, the radially outer securing contour engaging the concave depression to form a form-fit connection and preventing rotation of the heating device away from the mounting position;
• wherein the fluid conduit joining element is configured to be installed onto the tubular fluid inlet after the heating device has been mounted at the filter housing.
