The tool is assembled of two long handles (A, B) with cranked gripping areas (G1, G2) located at their upper ends. One of the handles (A) is provided with a longitudinal slot (L) below the gripping area (G1), accommodating a bolt (20) sliding along the slot (L) in order to adjust the distance between the jaws. The bolt (20) is assembled of a shaft surrounded by a helical spring, a cylindrical base, and a conical head, all accommodated inside a sleeve (16) and can only be moved when the head is pressed in order to release the locking unit.
