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 by its opening an engaging surface disposed substantially transversely 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, and two attachable standard parts forming nose-like end portions and adapted to be affixed to the head sections of the standard pincer-like members; the attachable standard parts forming the two nose-like end portions of the tool being each provided with two tips arranged symmetrically to a longitudinal center plane so that each nose-like end portion can be detachably attached to the head portion of the corresponding main standard part in two positions in which the two tips are successively brought into action are to thereby extend the useful life of the attachable part.
