Abstract
A molded base module for a filter assembly includes a header portion that defines a receiving cavity for a replaceable cartridge and may include integral inlet and outlet structures for communicating with the received filtered cartridge. The header portion includes an integrally formed retainer having a retaining channel for receiving tabs projecting from the cartridge, thereby retaining the cartridge to the module. The retaining channel is defined by a retaining lip and axially spaced shoulder connected by a side wall. In an illustrated embodiment, the retaining lip includes a plurality of angularly spaced axial slots and the side wall includes ramp-like projections which mate with correspondingly shaped tabs projecting from the cartridge.
