A fluid treatment device has an exchangeable treatment unit and a connection head. A bayonet-type connection device connects connection head and treatment unit to each other by a plug-in/rotation movement about a connection axis of the treatment device and is provided with a housing connection part and a head connection part that operatively engage each other to form a connection of the bayonet-type connection device. Housing connection part and head connection part each have a mutually complementary functional element extending circumferentially about the connection axis and operatively connectable to each other. The bayonet-type connection device has a pretension element for realizing a mechanical pretension pressing the functional elements against each other. A splash guard part is provided that covers at least the connection device.

A filter element has a filter material defining a raw side and a clean side of the filter element and to be flowed through by a medium to be filtered from the raw side to the clean side. A non-return element is disposed on the filter material. The non-return element allows a return flow of the filtered medium from the clean side back to the raw side and prevents a flow of the unfiltered medium from the raw side to the clean side. A filter and a filter system with such a filter element are disclosed. The filter system has a pump to supply medium to be filtered to the filter.
