A fastening device for a cleaning device by introducing pressure waves through a hollow nozzle into a boiler to be cleaned through an opening in the boiler wall has a housing body, which can be fastened to the boiler wall with the aid of a fastening flange on the boiler side, the hollow nozzle being concentric with the opening in the boiler wall and orthogonal to the boiler axis. Damping units are arranged at regular angular intervals around the hollow nozzle in the longitudinal direction thereof and are each fastened with one free end to the boiler-side fastening flange and with the respective other free end to the housing body. When the pressure waves are triggered, the housing body is resiliently retained in the longitudinal direction away from the boiler and brought back into the initial position.
