Abstract
A filter device for a filter system of a motor vehicle includes a filter element which is securable to a filter module. A filter element securing structure is disposed on the filter element where the filter element securing stricture interacts with a respective securing structure disposed on the filter module to form a bayonet closure. The filter element securing structure is an arc-shaped guide groove in a base of the filter element, where the arc-shaped guide groove has an insertion opening at a first end and a latching contour at a second end. The respective securing structure disposed on the filter module is a head pin that is receivable in the arc-shaped groove, An edge region of the arc-shaped guide groove slopes from the insertion opening to the latching contour.
