PURPOSE: A releasing prevention latch of a pipe connecting fitting is provided to prevent fluid leakage by preventing a screw from being released caused by outer mechanical vibration, the shaking of a piping and repeated thermal expansion and restriction. CONSTITUTION: A releasing prevention latch consists of a first and a second member(10,20) and a fixing pin(30) combining each member. A fitting body(1) is inserted into an inserting hole(13) of the first member and a union nut(3) is inserted into an inserting hole(23) of the second member. Then, four protruding portions(11,21) of the first and the second member are vertically arranged in a line to match each pinhole(12,22) of the protruding portions. After that, the fixing pin is inserted into the pinholes to solidly combine the first and the second member.
