Holder broken, I see. Easy! Hammer it just enough to hook the handle. Try getting it to, say, a 45 degree angle from where it is now. If you don't have a hammer, use a fist-sized rock. If you can't find said rock, as around to see if someone else has something you can use to bang on this.

Small bungees are cheap. Get a package and keep them stored somewhere in case this happens again.
