This is a simple plastic clip which fits over a servo connection (male to female connection) to assist in ensuring they do not wiggle apart during use.
Just snaps over the connected male-female pair.
Fits over standard “JR” style connectors.
That’s all, photos might describe it better, wires and connectors shown in the photos are not included, this item is just the orange clip part.
