A door locking device having a high anti-theft performance is herein disclosed. The device comprises a catching device mounted in the door and including a hook member and a lever member, the hook member being locked when the lever member is moved in a direction and unlocked when the lever is moved in an opposite direction; a key cylinder rotatably mounted to the door, the key cylinder being rotatable about the axis thereof only when handled by a specified key; an arm securely connected to an end of the key cylinder and extending therefrom radially outwardly; a rod pivotally connected to the arm and extending therefrom toward the lever member, so that rotation of the key cylinder about the axis thereof induces an axial movement of the rod; and a play providing device interposed between the extending end of the rod and the lever member, so that a play is permitted between the rod and the lever member upon relative movement therebetween.
