Abstract
The plug grip comprises a first and a second arms pivotally mounted together, with the first arm leading to a bearing shoe member and the second arm causing a raise of a screw of an expansion plug. The second arm comprises two successive bearing points, a first bearing point providing a great lever arm ratio for causing a start of bending of the expansion plug and a second bearing point providing a smaller lever arms ratio for increasing a distortion stroke of the expansion plug.
