4 Pcs Crocodile Clips, Alligator Clips, Small Crocodile Clips, Croc Clips, Crocodile Clamp Car Battery Clipon Socket Adaptor (Red and Black)

I just needed the clips in a medium size to connect a battery indicator, there are plenty of the tiny size and larger sets (jump start type) with cable which I already have, I only needed one set but it's always good to have a spare, these are the perfect size, strong grip, perfect opening for a car battery, well designed plastic covers with a locating pin so they don't slide off, even the small hole on the plastic end was the exact diameter of the wire on my device which was even better, highly recommended.
