A pipe coupling arrangement for coupling an end of a pipe section includes a coupling body having its open end, into which the end of the pipe section is inserted. An outer ring and a radially compressed inner ring are disposed in the open end of the coupling body. Inclined peripheries are respectively defined in the inner periphery of the outer ring and the outer periphery of the inner ring. These inclined peripheries are inclined so as to become smaller in diameter as they advances towards the open end of the coupling body. The inclined periphery of the outer ring and that of the inner ring are engaged by each other. A pressing means for pressing an outer periphery of the outer ring is provided such that the inner ring is tightly pressed against an outer periphery of the pipe section via the outer ring. A space is defined by the inclined surface of the outer ring and the outer periphery of the pipe section, into which the inner ring is inserted.
