I was a hamfisted hack when it comes to opening plastic electrical connectors. They stood a 50/50 chance of not breaking when I opened them, and were limping along held together with tiny zip ties. But no more, slip one of these tiny 90 degree picks up underneath the edge of the female connector, probe around a bit in her nether regions and... pop.. slips right off revealing shiny inner bits.
Usually $5 or so:
