Abstract: A threaded pipe (11) and coupler (5) made of polyvinyl chloride, the coupler (5) comprising two coupling ends having inner square-shaped threading (3, 14), each receiving a pipe end (4, 11) having an outer square-shaped threading, a sealing ring (2, 13) being provided between each coupling end of an inner surface of the coupler (5) and an outer surface of the corresponding pipe end (4, 11); a groove (10), being formed on the inner surface of the coupler (5), and co-operating with a part of the outer surface of the pipe end after the threading, when the pipe (11) is threadingly coupled in the coupler (5), to form a tangential hole (42) between the outer surface of the pipe (11) and the inner surface of the coupler (5) with the groove made on the outer surface of the coupler aligning with a groove of first pipe, wherein a wire lock (41) is inserted in the tangential hole (42) to lock the coupling of the coupler (5) with the end of the pipe (11).

Abstract: A Polyvinyl Chloride Threaded Pipe Joint System With Coupler & Wire Locking device comprising two pipe joining components, two sealing rings, including a wire lock, the said wire lock is component being inserted into the groove which locks the coupling with the one end of the pipe joint, the said coupling joining the both the ends using the threads, the said threads are made in the form of square type threads and the said sealing rings are fixed to the both the ends of the pipes and coupler.
