Improved strap wrench for tubes characterized essentially by consisting of a lever arm that at one of its ends widens forming a rectangular window crossed at its center by a pin that joins both sides; a trapezoidal section throat follows the window; this same end seen in profile has on its sides a curvature adapted to adapt to that of the tube to be fastened. The lever arm will be completed with a tape, independent of plastic fiber and that will be placed in such a way that going through the throat after hugging the tube, the single actuation of the lever will determine its tension and the consequent friction that will bring as consequently the perfect fastening of the tube to the key.
