This is the "McGizmo" 20mm Nano stainless steel gate clip. It has a spring gate which keeps items secure, and has a hole at the end for a standard split ring. Use this as a much better option over standard split rings, allowing quick addition or removal of items.

This model provides a stronger and more secure gate and is easier to handle than the smaller 15mm model, at the cost of a slightly larger overall size.
