Abstract: The present invention relates to a fastening means (1) of ceramics for fastening a refractory lining, wherein the fastening means (1) comprises a hollow shaft (2) which can be inserted into a recess left open in the lining and has a positive locking element (10) provided at its free end (9) as well as a collar (3) projecting beyond the shaft (2) at its other end which can be applied at the outside of the lining. For improving this known fastening means with respect to a secure protection of the metallic fastening part from the atmosphere in the combustion chamber, the present invention suggests to provide an undercut opening towards the hollow shaft in the region of the other end.
