The outer seal is circumferentially continuous relative to the connecting axis. A closure element is provided to close off, when the filter is connected to the filter head, a fluid drain in the filter head provided for draining fluid when removing the filter from the filter head. The outer seal is acting sealingly at least in radial direction relative to the connecting axis.
