If there is plenty of room and you can hook the broken ends together, then streteh the spring slightly between two brads and dab a little epoxy on the joint. Let is set overnight, and you should be good to go. Else find a retired watchmaker, or some old geezer (like me) who never throws anything out. He should have a jar of springs in the workshop and can probably give you one that will do the trick. We're not talking rocket science here.
