ABSTRACT:
A tubular fitting used for the connection of pipes, is formed such that if a main pipe and a branch pipe are inserted respectively within a through hole and a branch hole within the main fitting, and are coupled with the main fitting by means of the engaging body being engaged with the branch pipe and the branch pipe being engaged with the main pipe, the main pipe and the branch pipe can be securely connected by mechanical means without having to perform brazing operations.
