Abstract
A filter structure of inexpensive design that reliably prevents rotation of a filter housing with respect to an outer sleeve of the filter structure is disclosed. More specifically, a connector portion of an end cap of the filter structure is keyed with an opening provided in a receiving end of the outer sleeve to prevent rotation of the filter housing with respect to the outer sleeve. Keying is preferably accomplished by forming the connector portion of the end cap in the shape of a "Double-D", although other shapes may be readily employed.
