Please listen to Jay and buy yourself a new leash. As he mentioned, check the tie cord, the leash plug, etc.
PS - I always thought leashes were made from urethane?
Leash ends are heat welded on.
You can reproduce the heat welding at home.
Just don't use a naked flame, the charring will make a weak joint.
Use it as a small day leash.
Used to do it loads, never failed in the same place.
I even made a leash welding jig for a engineering module at college
Just a few points.
Heating a leash is about the only way to repair it. One that's been repaired should be relegated to small wave days.
If a broken leash means the difference between life and death, you're out in conditions beyond your abilities.
Leashes are made of urethane, not neoprene.

or just go leash-less...................
