I just changed my right inner and outer tie.

Yup. If you're trying to reuse the old clamp that had a crimp in it, you have to pull that crimp open first, typically with a pliers while holding the strap in a vice. Then you need the crimping tool to reinstall it. You can also use a side cutter, (wire cutter), to crimp it but I usually find access is too limited for that. Chrysler has some straps that you wind around once or twice, then tug them tight and bend the end over. Those are long enough to go around the large end of a cv joint twice. In a pinch you can even use a nylon tie strap. Hose clamps will work too. There isn't much pressure on that boot.
