Introducing the range of RS PRO Heavy Duty Crocodile Clips, a cost-effective and versatile solution for electrical measurement and testing applications. Designed using nickel-plated steel for durability, these clips are ideal for attaching wires or cables to establish a connection and freeing up the user’s hands.

Crocodile clips are most commonly used to create flexible, temporary or experimental electrical connections in a range of environments. This could be between two wires or between an electrical lead and the anode or cathode of a device (i.e. the entrance and exit points of an electrical current). They are incredibly versatile and can be found in many everyday environments like:

• Schools and universities to demonstrate the function of batteries, bulbs and circuitry


• Garages and vehicle maintenance facilities where battery charging takes place


• Welding or fabrication industries where they can help absorb excess heat

Alligator clips and Crocodile clips are the same thing, using either term is correct, and most people will know what you are talking about if you use either term.

A crocodile clip (also alligator clip) is a sprung metal clip with long, serrated jaws which is used for creating a temporary electrical connection. Functioning much like a spring-loaded clothespin, the clip's tapered, serrated jaws are forced together by a spring to grip an object.
