ABSTRACT:
A flexible extension tool for use with a conventional socket and ratchet wrench or the like comprising a helically wound flexible cable with end caps and rotatable conventional male and female connectors extending therefrom wherein the extension tool can be manually held in a highly bent configuration as a plurality of tongue and grooved cylindrical elements confined to the interior of the flexible housing spin therein during use thus transmitting torque. Each element consists of a cylindrical cross-sectional member with a centrally positioned radial groove at one end and an orthogonal centrally positioned radial curved tongue at the other end and a plastic washer or ring spacer positioned circumferentially thereon and coaxial to the helically wound flexible cable, thus partially occupying the annular space between the helically wound flexible cable and torque transmitting element resulting in smooth, low friction transmission of applied torque.
