description This invention relates to an expansion-control device (2), a piping tool (46), a method and uses for a packer body (52) on a mandrel (50) with a supporting ring (54; 58) arranged adjacent to an end (56; 60) of the packer body (52). The expansion-control device (2) includes a packer-control element (4; 4a; 4b) for positioning adjacent to the supporting ring (54; 58) and for radial movement relative to the mandrel (50); and a power-transmission body (6) connected to the packer-control element (4; 4a; 4b) for the transmission of activating power thereto. What is particular is that the power-transmission body (6) includes a lever body (8) with a fulcrum portion (10), and a lever arm (12) projecting radially from the fulcrum portion (10); the free end of the lever arm (12) being connected to the packer-control element (4; 4a; 4b); the lever body (8) being rotatable around a rotational axis (22) through said fulcrum portion (10); and the power-transmission body (6) including a torque-supplying device (30) to which the lever body (8) is operatively connected for the supply of torque to the lever body (8), and for the rotation of the lever body (8) around the rotational axis (22).
