These beautiful little clips are impossible to find. TriCor's part number was W2006 or 37-2006. They were originally installed on the BSA single rear brake rod clevis, then used with the first double-leading shoe front brakes of 1968. I don't think they used them after that, perhaps for budget reasons. It's just the trickest little item you've ever seen and allows very quick attachment/detachment of the cable/brake rod, and should suit other English cables. Cadmium verions are elsewhere in my store.
OD of the pin is just hair less than .250" , the spring clip is suited to clevis diameter of roughly .400"+/-. This listing is for one clip.
