A clip (also alligator clip or spring clip) is a simple mechanical device for creating a temporary electrical connection and is named for its resemblance to an alligator or crocodile's jaws.

Functioning much like a spring-loaded clothespin, the clips tapered, serrated jaws are forced together by a spring to grip an object. When manufactured for electronics testing and evaluation, one jaw of the clip is typically permanently crimped or soldered to a wire or is bent to form the inner tubular contact of a15 mm ~ 4 mm female banana jack, enabling the quick non-permanent connection between a circuit under test and laboratory equipment or to another electrical circuit. The clip is typically covered by a plastic shroud or "boot" to prevent accidental short-circuits.
