Abstract
The invention relates to a filter, especially an oil filter, comprising a carrier casing which borders a clean room/chamber. The filter also has a filter element which encloses the carrier casing. The filter element is comprised of zigzag shaped folded strip material, whereby the end folds of the filter element are adjacently held together. In order to construct the filter in such a way that a mass-production with a high operational reliability is guaranteed, a clamping strip which fastens the end folds of the filter element is arranged on the exterior surface of the carrier casing.
