Abstract
A cartridge filter has a filter element and a frame formed of plates. The plates are installable around the filter element and are interconnectable in the area of the sides of the plates. The plates have plug-in connection members which interact with corresponding plug-in connection members of adjacent plates to thereby affix the plates to one another.
