Device for holding a filter insert

The receiving device (1) receives the two plate-form filter elements (3, 4) of the filter insert (2). It has limiting side walls (1a) and a bottom (1b). The bottom is stepped in terrace form, thus forming height-offset receiving elements (10, 11) for the individual filter elements. There may be an insertion slot in one of the side walls through which the filter elements can be inserted.
