Three alligator clips: a bare standard-sized clip; a miniature clip in a yellow plastic boot; a large red Square D multi-function clip. Square D is an American manufacturer of equipment used to control and distribute electric power headquartered in Palatine Illinois.

A crocodile clip (or spring clip) is a temporary electrical connector, named for its resemblance to a crocodile's jaws. An electrical connector is a conductive device for joining Electrical circuits together A crocodile is any Species belonging to the family Crocodylidae (sometimes classified instead as the Subfamily Crocodylinae) Functioning much like a spring-loaded clothespin, the clip's two tapered, serrated jaws are forced together by a spring to make them grip a metal object. A spring is a flexible elastic object used to store mechanical Energy. One of the jaws usually has either a wire permanently attached or a banana plug inserted into it, for connection to an electrical circuit. An electrical network is an interconnection of Electrical elements such as Resistors Inductors Capacitors Transmission lines Voltage The clip may be partly covered by a plastic shroud or "boot" to prevent accidental short-circuits.

Smaller versions are used in electrical laboratory work. A laboratory (informally lab) is a facility that provides controlled conditions in which scientific Research, Experiments and These have a slightly different shape and are called alligator clips.

Large versions of these clips, called automotive clips, made of bare copper, are fitted to car jump leads, which are used to transfer energy from a charged lead-acid battery to a discharged one. Copper (ˈkɒpɚ is a Chemical element with the symbol Cu (cuprum and Atomic number 29 A jump start or boost is a term for a method of starting an Automobile or other Internal combustion engine -powered Vehicle which has a Lead-acid batteries, invented in 1859 by French Physicist Gaston Planté, are the oldest type of Rechargeable battery.
