I'm sorry, I think you're going to have to bite the bullet. A bowline-on-the-bight has to be the answer. At least it is easy to tie, and comes apart easily. Do you have a hook as well as a shackle on the bridle? - A standard chain hook would have to be augmented by something 'friendlier' to rope, probably with a locking gate.

I had thought that the climbers might have come up with a suggestion of a device from that world.

Could an Ascender be used?
