As shown, a pair, one red and one black of standard 4mm Banana plug joiners, that is, plug a male banana plug in one end, and another male banana plug in the other end, to join them, or another way of looking at it you could call this changing the gender of a banana plug from male to female )
Handy to chuck a couple of these in your connectors draw for those odd times you need to connect two banana leads together on the test bench for some extra length, or whatever.
