A split spring steel ring having a channel-shape cross-sectional configuration is sewn into the bottom cuff of a filter bag. The split ring is placed into the opening in the thimble plate of a plenum chamber by lapping the ring at the split and pushing inward until the diameter is reduced for insertion into the opening. The ring is then allowed to expand until the ends abutt at the split. The ring is maintained in its expanded condition in interlocking engagement with the opening by a thimble extension which extends through the ring below the thimble plate of the plenum chamber.

In a baghouse arrangement for filtering particulate matter from a gaseous stream including at least one plenum having a plate member provided with at least one opening defined by a peripheral edge for gas passage therethrough and at least one tubular filter bag with one of its ends for connection to said peripheral edge in flow-through communication with said plenum, the improvement comprising in combination: (a) a split ring attached to said one end of said filter bag and adapted to be inserted into the opening of said plenum plate member; and (b) a removable elongated rigid insert tube adapted to be inserted into said one end of said filter bag and into said ring; (c) said insert tube having an upper peripheral rib portion of a diameter greater than the diameter of said opening such that when said ring is placed within said opening said insert tube is fitted through said ring with the lower portion of said insert tube extending below said plate member and the upper peripheral rib portion being in abutting relationship with said split ring to thereby maintain same in engagement with said peripheral edge of said opening whereby said filter bag is releasably connected to said plenum plate member.
