Possibly. What might be a better solution for dual retention is latches on the ends, like some automotive connectors. That way you're only worried about squeezing between two points instead of four.
Alternatively, now that I think about it, there could be two pins like you have illustrated on the female connector, but with a wide tab for the latch on the male side so the user only has to squeeze in one place. The trick, though, is that we're only solving one of the issues with this. Apparently, a small number of properly-inserted and -stressed connectors are still failing. Uneven current loading seems the obvious culprit; what's less apparent (still) is why.
