What do micro:pegs do?

In schools, two of the most commonly used small board computers are the Crumble and the micro:bit. Both boards incorporate 4mm holes which serve as terminals for connecting external components. 

To simplify the connection of wires to the boards I have invented a simple little device named the micro:peg

How they work

About a centimetre of insulation is stripped from the end of the wire to be connected. About half of the bare end of the wire is pushed down though the 4mm terminal hole and folded back on itself. A micro:peg is then pushed into the hole to hold the wire firmly in place. Removing the micro:peg releases the wire. 

How they help in the classroom

A standard method of connecting components is to use croc to croc leads. These work well but when using them in my lessons I have experienced the following issues:
