Separating device with a separating element

A separation device for separating at least one liquid fluid from a gas, the separation device comprising:

• at least one separation element comprising a housing, a housing cover arranged at the housing, and a filter element arranged inside the housing, wherein the housing cover comprises a housing cover thread;
• at least one first gas passage arranged centrally in relation to a mounting axis of the at least one separation element for mounting at a connector device, wherein the housing cover thread is assigned to the at least one first gas passage;
• at least one second gas passage arranged radially outside of the at least one first gas passage in relation to the mounting axis of the at least one separation element;
• at least one connection element configured to connect the at least one separation element to the connector device, wherein the at least one connection element comprises a connection element thread and further comprises a conduit, wherein the housing cover thread is configured for screwing onto the connection element thread;
• wherein the at least one connection element further comprises a circumferential element adjoining the connection element thread, wherein the circumferential element extends in an axial direction of the at least one connection element into an interior of the at least one separation element;
• wherein the connection element thread and the circumferential element surround the conduit;
• wherein at least one fluid channel extending in the axial direction of the at least one connection element is disposed between the conduit and the circumferential element;
• wherein the at least one separation element comprises at least one contour element and the at least one connection element comprises at least one complementary counter contour element complementary to the at least one contour element of the at least one separation element;
• wherein the at least one contour element and the at least one complementary counter contour element are configured for confusion-proof interaction with each other upon intended screwing of the at least one separation element onto the at least one connection element;
• and
• wherein the at least one complementary counter contour element is arranged at the circumferential element and comprises one or more passages, wherein the one or more passages penetrate the circumferential element in a radial direction of the at least one connection element from an outer side of the circumferential element up to the at least one fluid channel.
