This significantly reduces costs while ensuring the pressure resistance of the pipe material, and the flexible and easily deformable pipe wall facilitates crimping connections. The inner support core of the pipe fitting is inserted into the pipe port of the outer locking ring sleeve. A ring pressing device causes the locking ring sleeve to radially contract and deform, compressing the corresponding part of the pipe material inside the locking ring sleeve that is fitted onto the inner support core, thereby compressing the sealing material between the pipe material and the inner support core to achieve a sealed connection. Simultaneously, the inner end of the locking ring sleeve is crimped into the groove of the connection between the inner support core and the guide fitting.
