For a swing suspended from a tree limb by ropes, one side has a little less rope than would be ideal to tie it, so over time it gradually slips out.
It's not a safety hazard like it sounds because it's obvious when it has happened and is in a high visibility area and there's plenty of forewarning, but I'd like to stop having to re-tie it every so often.
I was thinking of getting a rope/cable clamp of some sort but everything I've found seems to be expensive - is there something that is recommended here that would do the trick that would be reasonable? I don't believe much clamping power is needed given how the situation exhibits.
This is 1 inch thick rope (I think stranded twisted poly but may have the type wrong).
