1. improved releasable strap clamp joiner is used for the machinery and the hydraulic pressure interconnection of at least one end of first and second or connection set, and described joiner comprises:

  • A) center housing, it has the cross section that is similar to wide low wall groove, and the wall of described groove deviates from the center of described tube, and described housing is bent to the external diameter greater than described tube;

    B) the outer folder member of at least one bending, it is configured to contact the wall of described center housing, and the mechanical grip ring that is used to support annular seat component and is used to support inclination, the adaptive described outer channel of low wall internal channel of described outer folder member, separate between described low wall internal channel and the described outer channel preventing, near the end of the outer folder member of described bending at least one is set further and clamps extension part;

    C) the internal tooth carrier ring of Qing Xieing, it comprises a plurality of isolated wedge shape gripper unit, each unit is connected on two adjacent gripper unit by flexible member basically, to finish described carrier ring;

    D) at least one circumferential elastic member;

    AndE) spiral clamping element, it contacts with described clamping extension part, to reduce the distance between the described extension part, forces the internal tooth carrier ring of described inclination all circumferentially to contact with at least one tube with described flexible sealing component.
