Idk how bad it is, but without better pics I'd say cut it off where its torn, and if its nylon melt the ends, get a triglide and make a loop, ring some 550 cord through it and loop it on the skin swivel/ anywhere you can thread it through. If its broke worse then that upload soem pics and I'll try to help. If it is some plastic that broke you might be able to get replacements, but you could probably rig something up with 100mph tape and 550cord
