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. The refractory lining furthermore provided by the present invention comprises at least one refractory plate with at least one recess in which a metallic retaining element projecting from a furnace housing is received, a ceramic fastening means ( 1 ) connected to the retaining element which comprises a hollow shaft ( 2 ) projecting into the recess, the free end ( 9 ) of which is connected to the metallic retaining element, and a collar ( 3 ) provided at the other end which adjoins the lining as well as a ceramic plug received in the hollow shaft, and it is characterized in that the plug comprises a swelling received in an undercut ( 15 ) left open at the fastening means ( 1 ).
