A filter cartridge is suspended from a baghouse tube sheet by an array of generally vertical spring metal fingers which are welded to the upper edge of the filter cartridge. Each of the fingers has an inward projection, a bag cup having an external annular groove is suspended from the tube sheet. The filter cartridge is installed by pushing it upwardly toward the tube sheet. When the lowermost edge of the bag cup is engaged by the inward projections on the fingers, the fingers are cammed outwardly and the inward projections ride on the wall of the bag cup until they come into registry with the annular groove in the bag cup at which time they snap into the groove, thus latching the filter cartridge. A hosetype clamp secures the filter cartridge after it has snapped into latched position.
