A pair of 4mm 'Crock Clips' suitable for connecting metallic objects to E-Stim control units, via a 4mm cable. These clips are NOT suitable for connecting directly to human skin. (If you are looking for skin type clips then consider using E-Stim Systems Adjustable Bipolar E-Clips.)

They are however perfect for connecting home made electrodes or metal objects to cables that end with a 4mm plug.

Supplied as a pair with 4mm sockets.
