Removing broken tile spacers

[Canski]

As the title I have successfully laid tiles to my kitchen / family room but after knocking out the clips some have not snapped off cleanly and will need removing before grouting. 2 - 3 mm joints. 
 

What’s the best way of removing these without damaging the tiles ?

Needle nose pliers?

I had a couple of plastic Spacers sitting proud when I did my bathroom floor and the first one I tried to remove left a little fink in the tile. 

 

So I used a soldering iron to melt the other two below the grout line
