An annularly configured device for use on each earthquake restrainer cable of a bridge, which device, will deform due to its internal configuration upon the occurrence of an earthquake, if the earthquake stresses the bridge cable with which the device is associated excessively. The result of the stress is a visual indication of the cable's elongation as manifested by a "crowning" of the annular indicator and a shortening of its length. The specific configuration required of the annular member is one of a reduced thickness section of the interior wall, with tapered edges leading to the main cross section of the annular member.
