Quick-action coupling system for connecting a coupling piece (2) or another counterproduct to a pipe end (1), in which a clamping ring provided with internal teeth is present, which clamping ring can be tightened in the axial direction in order to generate a radially inward directed force on the clamping ring. According to the invention, the clamping ring (12) comprises a casing part which is provided with incisions, known per se, running in the axial direction from the end facing away from the end of the pipe, and with a series of sharp teeth, running in the peripheral direction, on the ends of the lips formed by said incisions. This makes the system suitable for flexible hoses of the type with a spiral-shaped hard reinforcement, sheathed with soft plastic, in the case of which a spiralshaped groove is produced on the outside. <IMAGE> |
