What MR said... Will one of these work?

They are extremely strong and very easy to use.
Can be a tad hard to make depending on your skills and the reason they cost a bit is because they use a suprising amount of rope to manuf.
Just need to watch out for sharp edges on the attachement points
They are the 'Ducks Guts' for joining straps, bridles etc as there is nothing to jam or bind or whatever
