Small missing piece (Yamaha 703 remote control)

[Runnerrr]

This little piece fell out when I opened my Yamaha 703 remote control. I've now assembled it together again and wonder if the part is necessery, or I can just skip it?

If it is necessary, where should it be placed?

it goes between the control cables to help stabilize them.
