An arresting device is pivotally mounted between two handles of a pair of pliers. The arresting device comprises a sleeve and a rod fitted into the sleeve. The sleeve and the rod are pivotally fastened at one end with the two handles. The sleeve has a receiving cell, a retaining piece disposed in the receiving cell, and a spring disposed between the retaining piece and a side wall of the receiving cell. The retaining piece is urged by the spring to retain the rod. The receiving cell is provided with a pin pivoted thereto such that the pin is corresponding in location to the movable end of the retaining piece, and that the pin can push away the retaining piece from the rod. As the pin is turned such that a recess of the pin is corresponding in location to the retaining piece, the movable end of the retaining piece is in the free state, thereby enabling the retaining piece to be urged by the spring to retain the rod.
