The filtration cartridge comprises a filtration element and a heat-resista nt extension band having a first and a second longitudinal edge. The first edge of the extension band is attached along an edge of the filtration element. In a fir st embodiment, a metallic cast end member is formed by immersing the second edg e of the extension band into molten metal. The molten metal is then allowed to solidify with the second edge of the extension band embedded therein. In a second embodiment, the extension band is squeezed on a porous inner core and an end plate is welded on the end of the inner core. Providing filtration cartridges with a metallic end member allows increasing their resistance to mechanical shocks and increasing their maximum operating temperatures.
