A filter assembly includes a base and a filter cartridge installed on the base. The filter cartridge is retained on the base by a radially expandable, resilient, circumferentially extending snap ring which is expanded by rotation of a camming member located between contiguous ends of the snap ring. The snap ring includes a lip which engages a groove on the filter cartridge to hold the filter cartridge on the base.
