The thing is a cheap replica. The patch tongue is made of soft metal and will wear very quickly (see product picture). Unable to push the cables neatly in the terminal, because the whole thing has too much play. Even with patch panels there are standards that ensure that fits a tool to the workpiece.
An original product, which it looks very similar here, comes with a hardened (usually blackened) pliers and therefore not with chromed metal, as here. Then it will come without frustration.
So rather spend a few euros more, if you want to invest more or more than a cable.
