Un-Pinning Tyco Slide-Lock Connector

[Citroënbender]

One of these, it’s not Ford so I haven’t put it in one of the Tech subforums. Looking for a suggestion on “cheating” (improvising).

They have thin, fiddly spring legs either side of the terminal “mouth”. I don’t have a release tool, and need to release the seven populated spots to reuse the un-damaged housing. A fine flat blade screwdriver doesn’t seem to be doing it, and sewing needles were unsuccessful as well.
