A Safe Auto-Locking Belay Override Mechanism (24) is provided which causes an auto-locking belay device to lock a rope against movement if a belayer panics, as sometimes happens if a climber falls, after the belayer has overridden the normal function of the auto-locking belay device. The mechanism of the subject invention makes use of the realization that a belayer tends to grip an auto-locking belay device tightly when the belayer panics. The subject invention contains a pressure sensitive activation means that acts on an override means such that the normal function of the belay device will be overridden by only one of three different force levels. At either relatively low or relatively high levels of force exerted by the belayer on the pressure sensitive activation means, the auto-locking belay device will function normally and lock a rope against further movement in the event that the rope exerts sufficient force on the auto-locking belay device such as when a climber falls. If, however, the belayer exerts an intermediate level of force on the pressure sensitive activation means, the normal function of the auto-locking belay device will be overridden such that rope can be fed rapidly though the device.
