PROBLEM TO BE SOLVED: To provide a locking junk ring of a tough structure which integrally has a lock hard to drop a locking pawl, which is easy to perform a locking work and which has relatively small size and lighter weight. SOLUTION: The locking junk ring includes the locking pawl movably engaged from a pipe side of a distal end side of a pawl hole intrusively to an outer peripheral surface of the pipe inserted into the junk ring, and the lock having a bolt for the locking pawl for intruding the pawl engaged into a bolt hole formed to communicate with a rear end side of the pawl hole, to the pipe. In this junk ring, the locking pawl is movably engaged within the pawl hole, and a pawl holding member made of a material having an elasticity and formed in a sectional wave shape is inserted from the distal end side of the pawl hole and is wedge stopped.
