Abstract
A hollow filter element for insertion into an openable filter housing has a filter medium body configured as a hollow body surrounding an inwardly positioned flow space. At least one end disk is connected to the filter medium body and covers an axial end face of the filter medium body. A positioning element is arranged at the at least one end disk and interacts with a housing-associated blade of the filter housing. The positioning element receives the housing-associated blade with form fit in two different transverse directions relative to the longitudinal axis of the filter medium body. The positioning element has a positioning recess.
