Open EDC16

[zi-pij]

Good evening to all
I have to disassemble a EDC16 change the connector.
Up to now I am only limited to open only the part above, but here I have to disassemble it completely.
I'm trying in all ways but I can't do it, can someone suggest me the exact way to not do damage?

Some malice, trickery......


Thanks and have a good evening
