A pipe system has a pipe with an axis and a retainer groove formed in an exterior of the pipe near an axial end of the pipe. The pipe system also has a tubular body with an interior and one end sized to receive the axial end of the pipe therein to form a pipe assembly. The pipe system also has a retainer configured to be received in the retainer groove and to be both axially movable and radially movable relative to the retainer groove during formation of the pipe assembly and to retain the pipe and the tubular body in the pipe assembly.
