Bungee Cord Splice, Is there such a thing?

[Neptunes Violin]

PS:

I like Stumble's idea. No reason you cannot break the runner into two pieces. So when not in use, the "upper half" is secured at the mast base.

When required, you take "lower half", connect it to the upper half and it's done.

Of course, there is the added expense of the splice fittings
