ABSTRACT:
A pincer-like tool for tightening clamps of the type provided with overlapping band portions each including an outwardly projecting embossment that extends generally in the circumferential direction of the clamp and offers an engaging surface disposed substantially transverse to the circumferential direction and located at the end of the embossment remote from the free end of the respective band portion. The pincer-like tool includes two main standard pincer-like members of punched-out steel plate material each having a head section and a shank-like connecting section, two handle members fastened to a corresponding one of the connecting sections, a pivotal connection pivotally connecting the two standard pincer-like members with each other in an area intermediate the head section and the connecting section, a nose-like end portion at each head section of the standard pincer-like members, the two nose-like end portions being so arranged as to approach one another when the tool is actuated by displacing the handle members toward one another, and each nose-like end portion being provided with a tip projecting outwardly from its end face in such a manner that an abutment surface is formed by the end face adjacent the tip for engagement with the engaging surface of the embossment as the tip enters the embossment in the circumferential direction of the clamp during tightening thereof.
