1. A towable, non-conductive, mechanically locking sprinkler fitting for making a fluid connection between irrigation pipes, comprising:

  • a polymeric tubular fitting member having first and second open ends for mating with a pair of irrigation pipes, said tubular fitting member including a laterally extending, bevelled lower surface for permitting said fitting member to be slid across a field without tipping;

    an orifice disposed generally opposite said bevelled lower surface for receiving a sprinkler riser;

    said tubular fitting member having an annular recess located along its surface which corresponds with a mating annular recess on at least a first of said irrigation pipes to form an annular cavity; and

    a flexible polymeric spline inserted into said annular cavity to form a mechanical lock between said first pipe and said tubular fitting member, said fitting being light-weight for easy towing and non-conductive so as to avoid electrocuting a user.
