Coupling connection for a fiber reinforced synthetic resin pipe

A coupling connection for fiber reinforced synthetic resin shaft, comprising a shaft having a connecting area at a distal end of the shaft, support means and coupling means for cutting the internal diameter of the fiber reinforced synthetic resin shaft, the coupling means being disposed concentrically to the shaft, the coupling means having a plurality of peripherally disposed teeth members on a circumference of the coupling means, the teeth members extending axially of the coupling means and having a circular crown diameter larger than the internal diameter of the fiber reinforced synthetic resin shaft so that the interior circumference of the connecting area of the fiber reinforced synthetic resin shaft assumes the form of a cutting circumference of the coupling means and form-lockingly engages the coupling means upon axial emplacement and simultaneous cutting of the cutting teeth members of the coupling means into the connecting area of the shaft,

• wherein the fiber reinforced synthetic resin shaft is cut by the teeth members into the shaft along its circumference conforming the internal circumference of the shaft to the shape of the teeth members, thereby non-rotatably joining the shaft to the coupling means so that the shaft rotates with the coupling means.
