There should be what we call a Whammy on the snare........It will be in the middle and slide up and down on the cable. Some are double aluminum ferrules and some look like springs. Just slide it over the end of the wire and if too big, add a small twig or whatever to take up the extra space and hold it on there tight. If your snares happen to not have a Whammy on them, I use stovepipe wire to hold snare in place ~~ Just wind it tight sorta like a spring........ I often wondered if a small piece of black tape would work.....or a small cable tie? Haven't tried it yet but bet it would work.....Good Luck!
