A tubular lock includes an inside assembly having an inside rose and an inside rose liner, an outside assembly having an outside rose and an outside rose liner, a latch mechanism including a latch, at least one of the inside assembly and the outside assembly having a spindle operably connected to the latch for retracting the latch and a handle connected to the spindle to turn therewith, and a fireproof cover having a longitudinal through-hole through which the spindle extends. The fireproof cover is mounted outside the outside rose liner and thus covers the outside rose liner. The inside rose liner, the outside rose liner, and the fireproof cover are engaged together.
