It took me a while to clear the cobwebs. i was trying to recall a device that was covered in Practical Sailor. It was back in a 2005 edition. It is called a Wrap Pin. I hope the link works.
Based in East Haddam, CT, the company trademarked the name—"Wrap Pins." Using high-strength glue, cotter pins are perpendicularly attached to a strip of heavy-duty Velcro. To use, insert the cotters (there’s no need to flare the legs) and wrap the Velcro round-and-round. The Wrap Pins are handiest for turnbuckles secured with pins in each of the threaded segments. But they can be used in other ways on shackles; if it's something critical, the cotter still should be flared first.
The picture shows how the pin on the right is used on different turnbuckles
