Abstract
A filter element (10) suitable for installation in a liquid filter for cleaning a freeze-endangered liquid; the liquid filter having a housing (37), composed of a housing pot (38), a housing cover (39), and a filter element (10) situated in the housing pot (38), with the housing cover (39) screwed onto the housing pot (38) in a sealed manner. The filter element (10) has a first end disk (11); a second end disk (12), and a filter medium (13) interposed between the end disks (11, 12). The end disks (11, 12) are mutually connected by a supporting element (30), which prevents radial relative movements between the end disks (11, 12). In the axial direction, the supporting element (30) has snap hooks (25) which connect the first end disk (11) undetachably to the second end disk (12). As a result of this connection, the second end disk (12) can be reliably removed from the housing pot (38) by pulling on the first end disk (11).
