Claim:
A filter housing of an air filter, the filter housing having a raw air inlet and a clean air outlet, wherein a filter element is insertable into the filter housing such that the raw air inlet is seal-tightly separated from the clean air outlet; the filter housing comprising: a first housing part and a second housing part openable connected to each other; at least one latching element securing said first and second housing parts relative to each other in a closed state of said at least one latching element; said at least one latching element connected to said first housing part by a moveable connection at least up to the point of first assembly of said first and second housing parts; said at least one latching element pivotable by said movable connection in a pivot movement into said closed state for latching said first and second housing parts; wherein said first housing part is formed monolithically together with said latching element, said latching element being unitary one-piece with said first housing part; wherein said at least one latching element has a positioning opening having oppositely positioned boundary walls that form a lower positioning element formed on a first one of said oppositely positioned boundary walls; an upper positioning element formed on a second one of said oppositely positioned boundary walls; said first and second housing parts each having a counter-positioning element, wherein said counter-positioning elements are projections on said first and second housing parts; wherein, in said closed state, each of said counter positioning element projections project into said positioning opening and rest against a respective one of said positioning elements of said at least one latching element; wherein, in said closed state, said counter-positioning elements are arranged between said at least two positioning elements of said at least one latching element, when viewed axially in an axial assembly direction of said first and second housing parts; wherein said positioning elements of said at least one latching element each form a stop in said assembly direction for one of said counter-positioning elements, the stops preventing the first and second housing parts from separating more than spacing between the lower positioning element and the upper positioning element; wherein said moveable connection has a predetermined breaking point; wherein said moveable connection is a film hinge formed into said first housing part, said film hinge forming said predetermined breaking point; wherein said at least one latching element has at least one element locking section that, in said closed state, locks at a housing locking section provided on said first housing part or said second housing part; wherein said predetermined breaking point is when said at least one latching element is locked and/or released from said closed state is subjected to a mechanical stress such that at least upon release of said at least one latching element said predetermined breaking point breaks, eliminating said moveable connection.
