Abstract
A filter element arranged exchangeably in a filter housing of a filter has a filter medium delimiting an element interior. An end body arranged at the filter medium has a fastening region surrounding the interior opening that communicates with the element interior. An insertion adapter for connecting the filter element to a fluid connector of the filter housing has an insertion sleeve insertable axially into the fastening region of the end body. The inward side of the fastening region is provided with a material that is initially flexible during manufacture of the filter element and hardens later on. The insertion sleeve has a holding element radially outwardly arranged at the circumference. With inserted insertion sleeve, the holding element is arranged in the fastening region. The initially flexible material of the fastening region flows behind the holding element and forms a form fit connection with the holding element when hardened.
