Gripping jaws are removably mounted to holders rotatably connected to the other ends of the levers, the gripping jaws being adapted to clamp a tube to be bent therebetween on opposite sides of the mandrel. A further cylinder is provided for moving the slides in a direction parallel to the axis of the mandrel.
