A system for tensioning and locking a safety strand to a plurality of sequentially arranged stanchions is provided. Each stanchion has a stanchion cross section and a passage bore adapted for slidable passage of the safety strand therethrough. The system comprises tensioning means for applying a tensile force to a first end of the safety strand when the safety strand is disposed through the passage bore of each of the sequentially arranged stanchions and a second end of the safety strand is secured to an immovable object. The system further comprises a plurality of locking mechanisms. Each locking mechanism comprises a cable cradle having a receiving channel configured for receiving a portion of the safety strand, a clamping arrangement adapted for engaging and trapping the portion of the safety strand within the receiving channel, and means for securing the cable cradle and clamping arrangement to a selected one of the plurality of stanchions when the safety strand is disposed through the passage bore of the selected stanchion. The cable cradle and means for securing are configured so that when the cable cradle is secured to the selected stanchion, the receiving channel is in registry with the passage bore.
