Abstract

An oil filter 1 for an internal combustion engine includes a filter body 3 and a plastic filter housing 2. Integrally formed within the filter housing, a safety wall 7 is radially fitted around the feed channel 4 and the return channel 5 creating a collecting space 6 that surrounds both channels. If seal leaks occur when the device is connected to a flange, e.g. of an engine block, the leaked oil will accumulate in the collecting space.
