What makes cables (USB, HDMI, etc.) “stay” plugged in to their ports?

Like, when you plug it in, what makes it “snap” into place and stay there? You’re just sticking an object into a hole, and it’s not like there’s a moving part that locks and unlocks it.

There little spring detents where a bent piece of springy metal snaps into a dimple/cutout made for it. It’s more secure than friction alone, but still loose enough to allow for removal without any sort of “unlocking” mechanism.
