ABSTRACT:
A filter assembly comprising a housing with a threaded open end, a filter element, and a cover assembly. The filter element includes a media ring and a pair of end caps, one of which includes outwardly-projecting fingers. The cover assembly includes a cover member, and a sleeve with recesses in an outer surface. A collar member surrounds the sleeve and is freely rotationally supported by the cover member. The collar member includes i) a threaded portion on an outer surface for screwing the cover member onto the housing, and ii) recesses in an inner surface. The collar member is rotatable relative to the sleeve such that the recesses in the collar member and in the sleeve can be aligned, and the fingers can be inserted therebetween, to rotationally lock the collar member relative to the sleeve and to retain the element with the cover.
