Definition
A spring-loaded electrical test clip with serrated, jaw-like tips that grip a wire, terminal, or component to make a temporary electrical connection.
Plain English
A small metal clip with toothed jaws and a spring inside. You squeeze it open, attach it to a wire or terminal, and it holds on by itself so you can run a quick electrical test.
Context Anchor
Seen during aircraft maintenance, electrical troubleshooting, battery servicing, and when using test equipment.
Derivation
Named for its resemblance to an alligator's jaws — long, narrow, and lined with sharp teeth that grip whatever they close on. The name describes the shape and biting action, which is why it sticks even in technical use.
Why Pilots Care
Enables safe, reversible connections during electrical checks so technicians can verify system function without altering permanent wiring.
Intuition Check
Do not think of an alligator clip as a permanent aircraft connector. It is normally for temporary testing, servicing, or troubleshooting.
Example Sentence 1
The technician attached an alligator clip to the battery terminal to test the voltage.
Example Sentence 2
During a ground test, she used an alligator clip to temporarily ground the test lead before measuring resistance.
