Claim:
A fluid filtration device comprising: a tubular external shell defining a longitudinal axis; a first end plate secured to a first end of the shell; a second end plate secured to a second end of the shell; a cartridge plate secured to the shell between the first and second end plates, such that the first end plate and the cartridge plate define a filtration chamber, and the second end plate and the cartridge plate define an outlet chamber, the cartridge plate including a plurality of apertures configured to receive a plurality of filter elements assembled thereto; an inlet port joined with the shell to intersect the filtration chamber; and an outlet port joined with the shell to intersect the outlet chamber; wherein the cartridge plate is secured to the shell by a laterally split, outwardly resilient retaining band received in interlocking engagement with a corresponding inner circumferential groove in the shell, the inner circumferential groove being positioned adjacent to the cartridge plate, such that the installed retaining band prevents longitudinal movement of the cartridge plate toward the second end plate.
