For forming an electrical connection between a cable, which may be coated with a nondraining insulating material, and a ductile metal ferrule into which the cable is inserted a special compression tool is employed. The compression tool consists of a support and a punch, which tapers stepwise and is also tapered between adjacent steps so that the punch may progressively pull more metal into the depression formed by the punch and yet may be withdrawn easily from the depression.
