A tool for crimping a compression sleeve onto a pipe includes support arms [50] that rotate about fixed pivots [68], and which each carry a slidably mounted crimping jaw [52] that is supported by the associated arm [50] for rotational movement of the jaw about the longitudinal axis thereof, movement of the respective jaws [52] being guided by ramp cams [58] and camming surfaces [60] which are operative to maintain the end faces of the jaws in true parallelism with one another, despite the movement of the jaws [52] about an arcuate path, and, the rotation of those jaws [52] relative to the support arms [50], movement of the jaws being under the influence of sliding surface contact of the camming members in the absence of line contact, while at the same time a greater sliding area between the respective jaws and their associated support arms is provided, thus enhancing the durability of the crimping tool.
