A restrained pipe joint is provided for affixing the spigot end of a first pipe into the socket end of a second pipe. The pipe joint includes a circular restraining ring and a retainer ring which includes a groove ring and a plurality of locking segments. When the retaining ring is tightened, the retaining ring is forced against the circular restraining ring, thereby engaging the locking segment teeth into the spigot end of the first pipe. The groove ring abuts the circular restraining ring which holds the spigot end of the first pipe within the socket end of the second pipe.
