Could someone tell me if there's a general name for the kind of spring clips that slide onto a rod and set a position for some other attached element. I've seen them on sinks and toilet tanks -- here are pictures:
After doing some searching it seems that style of clip is limited to toilet hardware like you have shown.
A google reverse image search found the originating site of your first image. They call it a "joint clamp clip" but a join clamp clip on wiki says "Joint clips are used to prevent a joint from separating during a reaction process" so that name does not fit.
Many niche industries and unique devices do not have names even if the device is very old. I'm sure various plumbers refer to this clip in many different ways. From my experience in construction, the names are often unintelligent, named after a specific brand of that product, racist, sexist, or overlap with another industry.
When I am creating engineering documentation and I see a new device that does not have an obvious, appropriate, or searchable name; I will often create a name for it. If the name is logical and valuable, searchable documentation is spread with that name; it may very well become the industry standard name for it.
Here potential names for it. If you like one of them set it as the alt text for your image; and you may have just named it ;-)
