These cord locks work well. They are comfortable, stay in place and remain taut even after exposure to heat (drying). I have replaced all the locks/switches on my mask with these. They are easy to apply and no needle is needed. All you really need is a piece of string to wrap around the rubber band and thread the ends of the string through the lock. The elastic must first be passed through the large hole, and then slowly pull the elastic all the way through the smaller hole.
