A portable, hand-held string tensioning device for tensioning a selected string portion of a sports racket includes a support bracket attached to the body portion of the device for supporting the body portion against the outside peripheral surface of the racket frame, a rod whose forward end is slidably attached to the body portion of the device and is movable relative to the support bracket, and a clamp for selectively clamping an end of the string portion protruding through one of a plurality of apertures located along the outside peripheral frame. A hand trigger is pivotably connected to the body portion and is adapted to engage and advance the rod in a forward direction to tension the string portion. The hand trigger is positioned such that it can be operated with only one hand.
