Economical, easy way to transfer pet ID tags/charms from collar to collar. No longer do you have to remove the tags/charms one by one from a split ring. This clip keeps all them together, so when you place tags on the collar or remove them from the collar, they can all move at the same time. Nickel clip fits any D-ring on collar and features a tension clasp that's easy for you to use, but foils pets. Clip measures 5/8" x 7/8". Nametag sold separately.
