The present invention relates to a readily replaceable liner for a detonation chamber (1) intended to protect the inside of the chamber from damage when the detonation chamber is used for test firings of fragment-producing charges. The liner consists of a plurality of readily replaceable parts or sections of a few types. In the case of cylindrical detonation chambers (1), use is made primarily for protection of the mantle wall of the chamber of rectangular plates or cassettes (20) slightly cupped in one direction, which are held together by a special fitting (29) to mantle rings covering the inside of the detonation chamber wall (10). The joint between the various parts of the liner is such that a small amount of play or rattle exists between the parts. By this means, the liner is prevented from commencing to vibrate in phase with the chamber wall (10). The fundamental idea behind the invention is a readily replaceable liner capable of receiving fragments and in which only damaged parts need to be replaced.
