PCT No. PCT/SE93/00291 Sec. 371 Date Oct. 6, 1994 Sec. 102(e) Date Oct. 6, 1994 PCT Filed Apr. 5, 1993 PCT Pub. No. WO93/19897 PCT Pub. Date Oct. 14, 1993.A crimping tool includes first and second jaws (1, 2) which are journalled at a first pivot point (5) for pivotal movement relative to one another. A forward end of a first handle (6) is rigidly connected to the first jaw (1), while a forward end of a second handle (7) is pivotally connected to the second jaw (2) at a second pivot point (8). A linkage construction (9) extends obliquely rearwards from a third pivot point (10) located on the second handle (7) rearwardly of the second pivot point (8), up to a fourth pivot point (11) on the first handle (6). The distance (D) between the first and the second pivot points (5, 8) is 0.30-0.35 times the distance (A) between the first and the fourth pivot points (5, 11), the distance (C) between the second and the third pivot points (8, 10) is 0.20-0.25 times the distance (A) between the first and the fourth pivot points (5, 11), and the distance (B) between the third and the fourth pivot points (10, 11) is 0.62-0.66 times the distance (A) between the first and the fourth pivot points (5,11). In the closed position of the jaws (1, 2) a plane (E) which contains the second and the third pivot points (8, 10) defines an angle ( alpha ) of 165 DEG -180 DEG with a plane (F) which contains the third and the fourth pivot points (10, 11), with the apex of the angle facing away from the first handle (6).
