A method and device for eliminating torsion during the servicing of cable heads. The device is a tool with a handle portion and clamping members having an opening and gripping surfaces for receiving and gripping two different cable-heads for servicing, such as attachment or detachment. When the handle portion is squeezed and held, the tool provides a compression force substantially parallel to a common central axis of the cable heads. The arrangement of the tool prevents undesired load on the cable heads, optimizes the efficiency of servicing while preventing damage to the cable-heads.
