A housing for fluidically connecting an exhaust gas line to an exhaust gas heat exchanger, wherein the main flow channel of the housing extends in the direction of a central axis (X), from an inlet opening to an outlet opening, with an average flow cross section (SQ). In the main flow channel, at least one opening is provided in the housing for a valve shaft, and on the housing, at least one bypass opening formed by a connecting piece is provided between the inlet opening and the outlet opening. The housing is formed by a maximum of two deep-drawn sub-shells made of sheet metal, wherein the connecting piece is formed circumferentially around the bypass axis (Y) for connecting an exhaust gas heat exchanger via the upper shell and/or via the lower shell.
