Product review (4 stars): It's what broke
I can't give a replacement part five stars, because it had to be replaced to begin with.  The part was exactly what my washer needed.  I had to re-seat the cable once and now it is happily earning its value in not having to go to the laundromat.  As others have said, retain the mounting screws from the original.  Additionally, it's worth it to track down the installation manual.  The metal retention clips required pliers to free the failed latch cable, as well as the push-in hanging hook.  Remember to take off the (in the Whirlpool Cabrio) wire block plate from the back.

For those who did what I did first and tried to fix the innards of this, there are two bright metal strips bent in a couple places which came loose from I don't know where, and that is what failed.  They didn't look like they would attach anywhere, so maybe they are loose metal bits in the first place, but I never found where they go.  My time is eventually worth something, so buy one of these and save yourself electrocution, frustration, and annoyance.  There is a useful electric motor in the broken part if you fancy electronics scavenging.
