A door stopper device mounts to the pivot joint of a door hinge and provides a mechanical travel stop to adjustably limit the rotational range of the door. The device includes an elongate, curved hinge-mounting body having a split sleeve construction defining a space configured to receive the pivot joint of the door hinge. A circular end structure is disposed at each axial end of the sleeve body. An axially-extending and screw-receiving threaded passageway is formed in each end structure. During installation, after the sleeve body is mounted to the pivot hinge of the door, a set screw is threaded through each end structure passageway to form a respective press fit connection with one end of the hinge pin to secure the device to the pivot joint.
