Abstract: An improved speedometer cable housing release and removal tool for disconnecting a speedometer cable housing from the speedometer head of an automobile or the like. The tool has an elongated curved body portion or handle with a linear portion at one end of the handle and extends to form a combination fulcrum-guide that is disposed generally in a plane perpendicular to the handle. The combination fulcrum-guide has a bending radius along a cable housing receiving groove permitting the tool to straddle the speedometer cable housing, thereby permitting the speedometer cable housing to serve as a finder for the tool. A depressing arm is connected to and proceeds from the combination fulcrum-guide generally parallel to an axis extensive through the linear portion of the handle. The depressing arm is of adequate length to reach a release trigger which is attached to the speedometer cable housing.
