Bungee lock

This is a simple locking mechanism for a bungee cord tie down.
It is designed for bungee cord diameter of approx. 3.75mm to 4.25mm.
The concept is very simple. While the cord is in the larger holes, move the lock toward the bite of the bungee cord where you are tying down. It is best to collapse on the target while the lock is slanted to keep the cord in the larger holes. Once tight, squeeze the cord toward the center of the lock.

I have added a second version with a closed hole. The bungee cord threads through these holes. If you have a bungee with a ball on the end and don't want to cut it, the "open" hole version can be used. Just squeeze the bungee cord in from the side.
