PURPOSE: To manufacture a compressible tube joint at a low cost while maintaining rapid connecting technique by casting or molding an area basic body characterizing the type of the tube joint, such as T-type branch or a reducing shift part, from metal or non-metal material.

CONSTITUTION: An area characterizing the type of a tube joint is formed as a cast or molded basic body 2 fabricated from metal or non-metal material. This basic body 2 is fixedly connected to standardized connection parts 3, 3a, 3b made of sheet metal. These connection parts 3, 3a, 3b have protuberant ends 4, 4a, 4b holding O-rings 5, 5a, and cylindrical areas 6, 6a, 6b connected thereto. These cylindrical areas 6, 6a, 6b are provided at the ends with recessed parts 7, 7a, 7b acting as stoppers for the insertable flat-ended tube.
