A coupling and seal for fluid conducting piping and particularly adapted to plastic pipe, to quickly couple sections thereof, and utilizing elastomeric seal rings pressed so as to frictionally engage onto one tubular member to thereby connect it to a second tubular member. The invention resides primarily in a tubular coupling member and cooperating nut which together form a ring groove in which a seal is pressed and/or pressured so as to constrict onto the said second tubular member. A feature is the quick make and break connection that is provided, utilizing a bayonet slot with nut lugs cooperating with extended inclined planes and a stop to limit seal distortion.
