An old safety trick they used to teach us in auto-tech school was to get a section of small chain and feed it through the coil spring and then make a loop and use a padlock and lock the end around the frame somewhere. This way if it ever lets go, there is a safety chain holding it from ricochetting across the room, or into your chest. Kind of like the same theory on why there is that little section of safety wire that is attached to any hanging lamp in your house. It keeps it from crashing down on your head if the mounting bolts goes south.
