Crocodile clips, also called alligator clips, refer to small spring-loaded mechanical devices designed to clip on or connect wire ends, batteries, or other components in electronics and electrical engineering. Resembling structures like crocodiles' jaws, these clips provide temporary electrical connections with their highly firm and flexible spring exerting force on the integrated serrated jaws–gripping objects. A crocodile clip also features a small metallic, insulated (plastic or rubber covered) handle to easily open or close the jaws, protecting against accidental short circuits. Depending on the requirements and applications, alligator clips come in varied sizes, colours, materials, and designs.
Benefits of Using Crocodile Clips
Crocodile clips offer various benefits, including:
- They provide quick and easy temporary connections.
- They are lightweight and cost-effective.
- Allow easy attachment and detachment.
- Provide robust safety due to their insulated handles.
- Serrated jaws and flexible springs allow an easy grip on components without causing damage, especially to sensitive components.
- Allow hands-free operation and can be reused.
- Made of quality materials, and come in varied designs, sizes, and colours for easy identification.
- They are versatile and can be used for a wide variety of troubleshooting and testing applications in industrial and educational facilities.

Crocodile Clips, Kelvin Clips, and Automotive Clips: The Key Difference
Crocodile clips, Kelvin clips, and automotive clips are types of electrical connectors used for various purposes. They differ from each other based on their applications and design features. Crocodile clips are versatile and commonly used for general-purpose temporary connections, Kelvin clips (4-Wire Kelvin Clips) with four-wire configuration are specialised for accurate resistance measurements, and automotive clips (also called plier clips or battery clamps) are tailored for rugged automotive applications, with thick insulated cables.
Typical Applications of Crocodile/Alligator Clips
Crocodile clips are extensively used for a variety of purposes in multiple settings, such as:
- Jumper Cables: Alligator clips are commonly found at the jumper cables' ends to jump-start vehicles with dead or weak batteries. They temporarily connect the batteries between two vehicles to transfer power and start the engine.
- Power Supply Connections: Bespoke clips can temporarily connect power sources, such as batteries or power supplies, to various devices or circuits for testing or powering small projects.
- Test and Measurement: Crocodile clips are commonly used in electronic testing, circuit debugging, and measuring devices, including multimeters, to measure resistance, voltage, and current.
- Battery Charging: Alligator clips are used in various battery charging applications, such as charging lead-acid batteries or connecting solar panels to batteries for charging.
- Automotive Repairs: In automotive repair work, crocodile clips are used for various purposes, such as testing electrical components, grounding, or creating temporary connections for diagnostic equipment.
- Educational Settings: These clips are often used in educational settings, including laboratories, allowing students to understand and experiment with electrical circuits in a safe and easy-to-use manner.
