I had that exact binding, although it broke in a different spot. Called CWB, talked to a great guy who mailed my the part and told me how to fix it. Got it in the mail in 3 days, took me 20 mins. to fix. They'll replace the whole binding if needed, but this was faster for me.
here's the link for the return policy info and phone numbers:
