ABSTRACT:
A filter bag which includes an annular thin-walled band having a plurality of discrete resilient tabs extending from its outer surface along two axially separated paths. A flexible collar is secured to the outer surface of the band and conforms to the shape of the tabs to provide discrete protrusions along the two paths. The band and collar assembly is secured to one end of the filter bag. The end of the filter bag can snugly fit into a socket of a cooperating member, whereby a portion of the socket is positioned in the space between the two separated paths and is retained by the protrusions disposed on either side thereof. The retained portion of the socket includes an enclosed annular ring.
