Sometimes they're mini hooks or similar, and there are other makers, I've got some Pomona mini grabbers that do a great job and probably come with a bit higher gauge wire, but they are typically expensive. You can sometimes catch a lot of used ones on ebay for relatively cheap, you can also buy just the hook individually for very little, then build your own cable/strain relief onto it.
I wouldn't use those on ICs, though, I use them on headers/cables. I'd look at test clips for logic analyzers, as they'll be a smaller size and better suited for work with ICs. There have been some discussions on ones for really precision work, but you can get very inexpensive ones with 0.1" header connections coming out of them, or you can get nicer quality ones like the HP 5090-4833 - I picked up a handful of them for about $1 each a while back on ebay sold secondhand.
