A coupling for joining two pipes in end-to-end relationship includes flanges which are sealably secured to end sections of pipes to be connected. The flanges form front inclined faces and adjacent front flanges that are slidably received within opposite end openings of a cylindrical coupling. A groove or shoulder is formed at the rear end of the front flanges that cooperate with jaws extending from the ends of the cylindrical coupling to secure the received pipe end portions in the cylindrical coupling to thereby join the pipes together. One or more gaskets fit in the cylindrical coupling between the ends thereof with gasket arms that abut against the inclined surface so that fluid pressure in the pipes force the gasket arms against the inclined faces to provide a seal between the joined pipes. A stop may be provided to limit the sliding travel of the cylindrical coupling with respect to the flanges.
