Abstract: A wire end connector tool designed for use with a standard wire connector cap for crimping the ends of wires together. The tool consists of a cylindrical handle of a thickness to fit comfortably in a user's hand and an axial member, longer than the handle, rotationally captured in and extending through the cylindrical handle and able to rotate therein. One or both ends of the axial member protrude from the end(s) of the cylindrical handle. Each protruding end is formed into a helical coil with its axis parallel to, but spaced from, the axis of the handle. Each coil is designed to securely accept standard wire connector caps such as those described above and to prevent it from rotating. This allows wires to be connected with a simple wrist rotation rather than requiring manual twisting with the fingers.
