Bungee cords are one of those things that seem to always need fixing. The good news is, it's a relatively easy fix! All you need is a few tools and some patience and you'll have your cord fixed in no time.
First, you'll need to remove the damaged portion of the cord. Use a sharp knife or scissors to cut through the cord at the point where it is frayed or otherwise damaged. Be sure to make a clean, straight cut so that the new end of the cord will be able to be properly secured.
Next, take your new piece of bungee cord and attach it to the old piece using a strong knot. There are several different knots that will work for this, but we recommend using a square knot or a sheet bend knot. Once your new piece is securely attached, trim off any excess cord so that it's flush with the old piece.
Now all that's left to do is secure the end of the cord so that it doesn't come undone. You can do this by tying another knot in the end of the cord or by using a crimping tool to clamp down on the end of the cord. Either way, be sure that your repair is secure before using your bungee cord again!
