The French Fury and her new blower motor

Hello guys,
I just purchased a new blower motor, and I have to connect it to the wiring.
On the left, the old one, and on the right, the new one. View attachment 413809
How can I remove the wires from old connector to re-use the connector on the new motor wires? Is it at least possible? I tried to insert a very small flat screwdriver, but the connector seems very fragile.
Or do I have to purchase a new connector, if yes, any lead appreciated, because in France, there's no way I can find...
