@Ridz, let me look. If I am not mistaken, its a see through plasic green clip, with a little step(hook) on the inside of the clip, that the swivel clip into?
I have found a cheaper yet greater quality option.
The Mustad safety clip is a copy of the old nash safety clip - circa 90's. It uses the same Pin as the Nash clip does to secure ones clip onto the swivel.
The new Nash safety clips use a cheap plastic that once submerged becomes very brittle. Even whilst packing up and pulling the tail rubber down by hand the arm breaks clean off. - last year i spoke to Simon Crow about the problem, and alot of other anglers worldwide agreed and had experienced the same problems. he promised to speak to Kevin but i didnt hear anything back.
The mustad clips are a strong plastic and to test them i have bent the arm the opposite way and it doesnt break off it just bends.
I prefer the fox ones. no need for mods if using 4oz+ leads. Dont pull the tailrubber all the way. It doesnt have such an acute angle therefore ejecting better than the more aggressive bends ie nash, korda
