Fluid filter elements and assemblies are used to separate contaminants from a fluid, such as oil or fuel, prior to reaching an engine. Fluid filter assemblies may comprise a housing, a filter element, and a filter head. The filter element may be disposed within the filter housing and enclosed by the filter head. Fluid enters the housing and passes through the filter element. The fluid may then exit the assembly. A connector may be used to connect the filter element to the filter head to ensure proper installation and simplify removal of a fouled filter element. The connector permits removable coupling of the filter element to the filter head and resists unintentional disengagement to securely couple the filter element to the filter head.
