I see a lot of latching SATA to nonlatching ESATA cables there. There's one 6 ft cable that says "metal latch" but nothing in the picture of the connectors looks at all like a latch.
Those results don't actually have a latch though. Like this one for example:
That's just a normal eSATA connector. So all eSATA connectors have a "latch" I think according to this one.
