ABSTRACT:
The invention relates to a link for a crimping tool (2) comprising at least two crimping dies (12,14,16,18) and two tool handles (6,8), where the movable link (23) is arranged between the tool handles (6,8), the link (23) having an opening (72) arranged to engage a guide element (70) on a first handle (6) and being pivotally fixed to a second handle (8), where the guide element (70) is arranged to move from engagement with a first edge (71) of the opening (72) into engagement with a second opposite edge (73) of the opening (72) when the handles (6,8) are brought together to a position where the workpiece (19) is engaged by the crimping dies (12,14,16,18), the link (23) thus enabling the person using the crimping tool (2) to utilize the optimum gripping range of the hand that is about to exert a large force on the handles (6,8) in order to bring them further together for the crimping of the workpiece (19), this regardless of the dimension of the workpiece (19) to be crimped.
