Abstract
A heat accumulation segment for local separation of a flow duct inside a turbo engine, from a stator housing that radially surrounds the flow duct is provided. The heat accumulation segment includes two axially opposed joining contoured elements that are engageable with two components that are axially adjacent along the flow duct. A first one of the two joining contoured elements has a radially oriented recess with a frustoconical contoured surface against which a securing pin having a frustoconical external contour that acts radially under force action from a component that adjoins the first joining contoured element, and the first joining contoured element has a collar portion having a radially upper collar surface and a radially lower collar surface. The collar portion is connected within a counter-contoured receiving contoured element in the axially adjacent component by a joining force that acts between the securing pin and the frustoconical contoured surface.
