Abstract
A liquid filter, in particular for internal combustion engines, having a filter housing with an essentially hollow cylindrical filter element arranged therein in a sealing manner to separate an unfiltered liquid side of the filter from a filtered liquid side. The filter element is supported on a connecting element having contours for forming a form-fitting connection through which the liquid filter is detachably and sealingly connectable to a counterpart. The counterpart may be a flange connected directly to a machine assembly, or it may be an adapter element for adapting the form-fitting connection to connect to a conventional threaded connector.
