ABSTRACT:
A filter assembly includes a housing for releasably locking to a base for enclosing a replaceable filter element. The base includes a support over which the housing is positioned. The support includes a plurality of radially extending guide pins. A plurality of radially movable jaws are mounted on the guide pins to releasably lock the housing to the base. A rotatable cam ring is coaxially mounted on the support and includes cam slots for receiving corresponding axially extending cam engaging portions of the jaws. The jaws move radially inwardly and outwardly to lock and unlock the housing from the base in response to rotation of the cam ring.
