Disclosed is a permanently fireproof flame guard comprising a flow area (2) which terminates a conduit and within which an inserted flame shield is disposed, said flame shield being provided with a plurality of passage gaps that ensure permanent fire safety. Cooling of said permanently fireproof fla me guard can be improved by forming at least one concentric, annular section (5 ) within the flow area (2) in a massive manner without passage gaps while forming annular sections (4) comprising passage gaps around said concentric, annular section (5).
