Clamping 1-inch rope - fastener

Question

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).

Answer 1

Overkill, but that's OK, - made for "wire rope" don't go overboard on tightening or you might damage plastic rope, but these are simple and inexpensive. Should be fine for just keeping a knot from coming loose.

If the location is near the user, you'll need to tape over the ends so nobody gets cut on the hardware.

On second thought, this might actually work better for the job you describe - plain old stainless steel worm drive hose clamp. Still needs taping over to prevent cuts if in an accessible location.
