Claim:
1. A filter element for installation in an air filter housing of a filter for fluid, comprising: an open filter bellows of a filter medium, which has an upstream side and a downstream side for the fluid to be filtered, and with an element axis, which is arrangeable parallel or axially to an installation direction for installing the filter element into the filter housing; wherein an element axis is an axis extending through the filter bellows from the upstream side to the downstream side; wherein the filter bellows has a first peripheral side extending from the upstream side to the downstream side of the filter bellows; wherein the filter bellows has an opposing second peripheral side extending from the upstream side to the downstream side of the filter bellows; wherein an X axis is defined as an axis having a direction traverse to the element axis and extending through the filter bellows from the first peripheral side to the second peripheral side; a seal running peripherally relative to the element axis arranged on the filter element; a first end plate having an upstream side edge, a downstream side edge, and opposing first lateral side and second lateral side edges, the first end plate having an inner side arranged on a first peripheral side of the filter bellows and covering the first peripheral side of the filter bellows from the upstream side to the downstream side of the filter bellows, the first end plate including: a filter element retaining device arranged on the outer side of the first end plate, the filter element retaining device including: wherein the seal is arranged directly on the one-piece protrusion and together with the one-piece protrusion forms an outwardly projecting convex U-shaped bump at least one guide crosspiece, the outwardly projecting convex U-shaped bump projecting in the direction of the X axis outwardly from the first end plate and beyond the at least one guide crosspiece.
