I'm trying to buy a few more of these things.

I guess it's some sort of shackle... but don't have a clue beyond
that.

Can anybody put a name on it?

Howcome?

Seems like with snap shackles the bail can get squinched over and
the whole thing can turn into just a hook.

The attraction of this thing for me is that once it's attached to
a steel ring and put under load, the scissoring of the
overlapping hooks seems to guarantee that it won't work loose.

All theory of course....

Bingo! "Scissor Hook" consistently returns good hits.

Thanks.

As does "Trigger Snap"... which seems more specific.

Two reasons.
If it's under load, it is held shut, but when shaken, i've seen 'em come undone.
They're not as strong. A scissor hook or a snaphook is not 'closed,' meaning that one side is supported by the other, so it can open if it deforms enough.
A pin shackle, a carabiner or a snapshackle may deform, but won't release untill the material breaks.

Definately a Trigger Hook. Depending on what you're using it for
though, search for inglefield clips; they may be better for what you
need.

I would call it a Widowmaker.

Im not sure why a person would use it on a boat when there are so many
other "safer' choices.

Pretty slick: no moving parts....

But my application is for attaching tie down straps to a roof
rack. The trigger snaps work well for that because they can be
easily operated while somebody is standing on tip-toe with arms
fully extended.

Spontaneous release does not seem tb an issue once they're under
tension.

Only caveat I've experienced so far is that it's possible to clip
them on is such a way that they're not fully closed - probably
because the ratio of jaw size to the size of the ring they're
clipping to is too small.
