I had an idear just now.
I had thought of the pvc thing before but I'd have to remove the wires from my SSCs to do it, and some folks here frown on ideas that have you crimp your own cables instead of buying premade patch cables. since by my thinking I'd also want a cap on both sides, of course if I needed a longer cable I'd need to buy more caps or cut the end off to salvage the cap.
I had considered using silicone tape but that stuff doesn't want to come off so decided it wasn't a good idea for a quick disconnect. But it just came to me what about slitting carboard tubing like a toiletpaper roll down the middle and putting it around the connector then encasing that in silicone tape, then if you need to pull it apart you could just snip the little bit touching the cable and slide it.
