Alligator and crocodile clips are useless in todays miniature
electronics. The best I can do are "wire hook" ends like these:

Perhaps someone should invent caiman clips. Ideally they would be sold
duty-free (=Cayman; geddit?).

Yuck. Hook clips work fine until one gets to boards full of SMT
components. I have a box of spring loaded probe tips, originally from
a bed of nails test fixture, positioned with the flex plastic hose
used for coolant hose and camera tripods. The board is secured to a
PCB holder and spring pressure makes the connection. Much better and
easier than tack soldering wires.

I'll be at home for a while longer so no photos but here are the
components:

I'd enjoy seeing pictures of your test bench setup with those pogo pins.
Near as I can figure you use those semi-stiff hoses to hold the pins on
the UUT (unit under test). For me, not su useful as I am mostly fixing
TTL stuff (not many folks still do that), but I can see it being very
useful on SMT products.
