Abstract
A filter construction particularly for vehicles and other spaces closed to the outside comprises a housing which has a filter compartment for containing the filter element with an opening to the compartment. A cover closes the opening and a locking mechanism for locking the cover in the closed position includes a slot defined in a frame portion of the housing and a lever member which is pivoted on the cover. The lever member has one arm portion with a nose which engages into the slot in the locked position and an opposite arm portion which carries a part of a bayonet joint which aligns with a complimentary part on the cover to fix the lever in the locked position. When the bayonet joint is released, the lever may be pivoted on the cover. The lever member has one arm portion with a nose which engages into the slot in the locked position and an opposite arm portion which carries a part of a bayonet joint which aligns with a complimentary part on the cover to fix the lever in the locked position. When the bayonet joint is released, the lever may be pivoted so that the nose moves out of the slot and releases the cover.
