Loose where the main arm that goes to the blade pivots, or loose where it's splined onto the shaft?
Or do you mean the "auxiliary arm" (the skinny one that makes the blade change angle as it comes up)? That one is attached to the pivoting blade-holder / bellcrank-sorta-thingy up at the tip (not too tight or it might bind) and just kind of sits on the pin down at the body end; no clip. The little hole and the pin will eventually wear a bit, and the arm may rattle. No big deal.
