Abstract

A filter element group for a filter device for filtering a fluid may include a ring-shaped working filter element, a ring-shaped protective filter element, an assembly device, and a securing device. The working filter element may include a ring-shaped working filter body, a first outer end plate, and a second outer end plate. The protective filter element may include a ring-shaped protective filter body, a first inner end plate, and a second inner end plate. The securing device may be adjustable between a securing state where the cover plate is axially secured to the second outer end plate and a release state where the cover plate is axially removable from the second outer end plate. When in the securing state, the securing device may secure the cover plate to the second outer end plate preventing rotation of the cover plate in the circumferential direction.
