A pipe disassembling tool includes a U-shaped body having a first arm and a second arm that can be outwardly wrenched relative to each other. The first arm and the second arm respectively have a curved cutout defined in a free end thereof and facing each other. A first curved pusher and a second covered pusher respectively extends from the free end of the first arm and the second arm. Each curved pusher corresponds to a corresponding one of the two curved cutouts. The first curved pusher and the second curved pusher are provided to outwardly the pawls of a coupling to allow the operator longitudinally detaching the pipe.
