A safe has, in addition to its strong body and door and its combination lock knob and dial, a security mask that is strongly and fixedly secured to the upper side of the door over major portions of the dial, for the purpose of preventing a burglar from hammering on the dial and then driving the spindle and actuating the relockers of the safe. In accordance with another aspect of the invention, an anti auto-dialer is fixedly connected to the security mask over the knob of the combination lock mechanism, to prevent operative engagement between the knob and an auto-dialer mechanism while at the same time permitting manual operation of the knob to work the combination.
