The one end is further provided with a radially outer sleeve, the sleeve having at least one continuous, radially inwardly directed annular barb formed on an interior surface thereof. The one end is adapted to receive one end of a length of flexible tubing between the sleeve and the tubular insert portion. A coupling assembly for supporting a sprinkler and for connecting the sprinkler to a supply conduit includes a coupling body having an axial through-bore, one end of the coupling body having a flexible tubing connector portion, and the other end of the coupling body having a screw thread formed thereon, adapted for connection to the sprinkler body. The flexible tubing connector portion includes an inner, open ended tubular insert portion, one end of which has a plurality of radially outwardly directed annular barbs on an exterior surface thereof. The one end is further provided with a radially outer sleeve, the sleeve having at least one continuous, radially inwardly directed annular barb formed on an interior surface thereof. The one end is adapted to receive one end of a length of flexible tubing of a first predetermined diameter between the sleeve and the tubular insert portion. The other end of the tubing is fitted with a connector and attached to a supply conduit.
