Abstract: A turbine engine casing, including a substantially cylindrical wall and a single-piece annular panel for acoustic insulation mounted radially inside the wall, is provided. The panel includes a radially outer annular surface fitted with upstream and downstream first projecting members respectively arranged in the upstream and downstream portions of the radially outer annular surface of the panel. The wall includes a radially inner annular surface fitted with upstream and downstream second projecting members that are releasably fastened respectively to the upstream and downstream first projecting members.
