A mouthpiece () for extruding a molding compound into a formed body which has internal channels, comprises: a mouthpiece frame () with a frame opening (); a first core retaining plate () which is fastened in the area of an upstream end of the frame opening () when viewed in the flow direction () of the molding compound; and a plurality of longitudinal cores () which are axially and laterally held by an upstream end section () on the first core retaining plate (). It is proposed that, furthermore, it comprises a second core retaining plate () which is loosely arranged downstream of the first core retaining plate () relative to the mouthpiece frame () in the flow direction (), and in which the areas () of the cores () farther from the upstream end section () are arranged to be radially fixed but axially loose.
