The Mueller's crocodile clip is insulated on both ends. The material used here for making crocodile clip is nickel-plated steel with PVC insulator. The current rating is 5A. It acts as a connector from both the ends. The large versions of these clips, called automotive clips or battery clamps, are made of solid copper. For low electrical resistance, it is used with thick insulated copper cables to make connections between automobile batteries.
