Abstract
Abstract An in-line crimping tool having a U-shaped die holder carried by links connected symmetrically to pivotally connected arms, a ram being mounted on the arm pivot and the geometry of the parts being such that the closing together of the handle ends of the arms causes the ram to advance in a straight line, guided by the sides of the die holder, to crimp or compress an object interposed between the die and the ram.
