Here’s a close-up of the quick-release shackle on the end of the tether that connects the safety harness D rings. This kind of shackle is opened by pulling on the cord with the red beads—it cannot be “snapped” into place like a snap shackle.
The quick-release shackle is considered secure and is used on the harness end of most tethers. It is unlikely that any unusual or twisting forces would be applied at this end of the tether.
