Here are some handy devices that will cheaply convert your Banana or TENS pins to a small alligator clip to connect many of your electrodes or DIY projects.  

Save over 50% when you buy 4 of these clips.  Get 4 for $6.95.  Just indicate you want 4 in the Drop-Down box.

The mouth opens to right at 3/8″ when fully opened and measure only 2 inches long.  A banana pin will fit nice and snugly into the end to convert your lead wire to a very useful clip.  To use with TENS pin leads you can simply push a small piece of 4x2mm conductive tube into the end and cut it flush with the end of the clip.  Your TENS pin will then push tightly and securely into the end easily converting to a TENS pin.  You can get a one foot piece of this tubing in our conductive tubing section of the web site.
