Described is a housing (18) for a separating device (12) for separating fluid from a gas, a housing cover (28) and a connecting part (16) of a device (12) and a device (12) for separating a fluid. The housing (18) has at least one first gas passage (82), which is centrally disposed relative to an axis (30) on a connection device (14). The housing (18) has at least one second gas passage (52), which is disposed radially outside the at least one first gas passage (82) with respect to the axis (30). The housing (18) has at least one fluid outlet (36, 48, 64) for fluid separated from the gas, which is disposed radially between the at least one first gas passage (82) and the at least one second gas passage (52) with respect to the axis (30). Between the at least one second gas passage (52) and the at least one fluid outlet (36, 48, 64), at least one housing-side fluid outlet sealing part (66) of at least one fluid outlet sealing device (92) is disposed, which is configured to sealingly interact with at least one corresponding connection-side fluid outlet sealing part (68) of the connecting part (16), which is provided for connecting the housing (18) with the connection device (14).
