Abstract
A recessed portion is formed on an outer periphery of a cylindrical joint body to be inserted into a joint mounting hole of a fluid pressure apparatus. A pull-out preventing ring which is formed separately from the joint body can be deformed elastically in a radial direction, and has one or more annular edge(s) on an outer peripheral face which is fitted in the recessed portion and over the outer periphery of the joint body. The annular edge(s) of the pull-out preventing ring is(are) locked to a hole wall of the joint mounting hole when a force in such a direction as to pull out the pipe joint acts on the pipe joint.
