A clip for holding a pair of nozzle inserts for use with an irrigation sprinkler includes at least two flexible attachment arms, each attachment arm provided with an elongated slot and a retention shoulder on an inside surface thereof, adjacent the elongated slot. Each attachment arm is adapted to be received in an opening in a respective nozzle insert and retained therein by the retention shoulder. A related tool includes a pair of gripper arms and a respective pair of jaws extending from the gripper arms, pivotally secured to one another. One jaw is formed with a pair of parallel prongs, and the other jaw is formed with a flat head projecting toward the pair of prongs. The jaws are adapted to engage the nozzle insert and disengage the retention shoulder to permit removal of the nozzle insert from the clip.

1. A nozzle insert in combination with a nozzle insert clip for loading into a complementary recess in a sprinkler body comprising: an insert body having an axis of rotation, a nozzle bore extending through said insert body; and a directional turning knob at a forward end of said insert body enabling rotation of said nozzle insert relative to said sprinkler body when the insert body is installed within said sprinkler body, said directional turning knob incorporating openings along a front wall of said turning knob and at one end wall of said turning knob, said turning knob receiving through one of said openings an attachment arm of the nozzle insert clip capable of holding at least two of said nozzle inserts, wherein said one of said openings includes an inside shoulder, the nozzle insert clip comprising at least two flexible attachment arms, each attachment arm provided with an elongated slot and a retention shoulder on an inside surface thereof, adjacent said elongated slot, said elongated slot defining a deflection zone for said retention shoulder, said retention shoulder engaging said inside shoulder by deflection of the flexible attachment arm into the deflection zone when the flexible attachment arm is received in the turning knob. 2. The nozzle insert of claim 1 wherein said directional turning knob is provided on a forward side of an end wall and wherein a pair of substantially parallel through openings are located on a rearward side of said end wall. 3. The nozzle insert of claim 2 wherein a rib that partially defines said through-openings is in substantial alignment with said elongated slot. 4. The nozzle insert of claim 1 in combination with a nozzle insert clip, wherein said at least two, flexible attachment arms hold said nozzle insert and at least one additional nozzle insert, and wherein said nozzle insert is located within the complementary recess in the sprinkler body while said nozzle insert and said at least one additional nozzle insert are held on said clip. 5. The nozzle insert of claim 4 wherein said nozzle insert clip is provided with three flexible attachment arms for holding said nozzle insert, said additional nozzle insert and a third nozzle insert. 6. A clip and nozzle insert assembly for use with an irrigation sprinkler, the clip comprising at least two flexible attachment arms; each attachment arm provided with an elongated slot and a retention shoulder on an inside surface thereof, adjacent said elongated slot, each attachment arm received in an opening in a respective nozzle insert, wherein said opening includes an inside shoulder therein, said elongated slot defining a deflection zone for said retention shoulder, said retention shoulder engaging said inside shoulder by deflection of the flexible attachment arm into the deflection zone when the flexible attachment arms are received in the nozzle inserts, the clip and nozzle insert assembly further comprising a tool for facilitating removal of the nozzle insert from the clip, the tool including a pair of gripper arms and a respective pair of jaws extending from said gripper arms, pivotally secured to one another about a pivot, and first and second jaws at opposite ends of said pair of gripper arms, respectively; one jaw comprising a pair of parallel prongs, and the other of said jaws comprising a flat head projecting toward said pair of prongs. 7. The clip and nozzle insert assembly of claim 6 wherein said clip comprises three flexible attachment arms. 8. The clip and nozzle insert assembly of claim 6 wherein said flat head extends substantially perpendicularly to said other of said jaws.
