新案登録請求の範囲第１項に記載の管継手装置。[Claims for Utility Model Registration] (1) Shape memory formed into an annular shape corresponding to the diameter of at least the end of the pipe to be connected, and deformed to reduce its diameter by thermoelastic transformation from a desired low temperature state to room temperature. In a pipe joint device that has a driver made of an alloy and connects the pipe ends of a pair of connected pipes to each other by diametrical deformation of the driver, the driver undergoes radial diametrical deformation during thermoelastic transformation. At the same time, it provides an action that can cause axial contraction deformation, and in addition to sealing the abutting ends of the connected pipes together by reducing the diameter, the abutting ends can also be directly connected to each other by the contraction. Alternatively, a pipe joint device characterized in that an indirect contact pressure connection is obtained. (2) The pipe joint device according to claim 1 of the utility model registration, characterized in that a gasket packing is interposed between the abutting ends of the pipes to be connected.
