Abstract
A pipe joint has a body having a through hole defined axially therein as a fluid passage, a nut threaded on the joint body thereby connecting the pipe to the joint body, and a sleeve held against a bottom of a hole defined in the joint body by an annular step surface and having a bulging portion slanting at a predetermined angle. The nut has a radially inner pipe presser which is bent and flexed into a shape complementary to the bulging portion when the nut is progressively threaded over the joint body, for pressing an end of the pipe against the sleeve under a resilient force tending to return the radially inner pipe presser to an original shape thereof.
