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.

A filter bag for interconnecting to a socket of a cooperating member comprising: a tubular filter member fabricated from a filter material; an annular thin walled flexible band having axially spaced apart edges; a plurality of discrete resilient tab means extending outwardly from an outer surface of said band, each of said tab means being defined by a free end struck outwardly from said band and a hinge line connecting each of said tab means to said band, said tab means being peripherally spaced apart from each other and being disposed along two axially separated paths around said band; a flexible collar secured to said outer surface of said band to define a band and collar assembly, said collar being disposed on said tab means with said collar substantially conforming to shape of said tab means to provide discrete protrusions along each of said two paths and a recess between said two paths of protrusions; said tubular filter member including retaining means for holding said band and collar assembly at one end of said tubular filter member; said one end of said tubular filter member being capable of snugly fitting into the socket of the cooperating member, whereby said resilient tab means are pressed inwardly to permit a portion of the socket member to be positioned in said recess between said separated paths, where said portion of the socket member is retained in said recess by the protrusions disposed on either side thereof.
