What is the name of this kind of tub spout and looking for a replacement (slip on?)

[Caccaco]

Here is what I took off the wall, its a nice all in one unit which is just secured with a single hex screw on the bottom there near my thumb:

And here is what the pipe on the wall looks like, it is 2.5" long, non threaded:

I would like to get a brushed nickel replacement but what I saw in Home Depot all needed adapters and such. I messed around with this one model, which needed an adapter: https://www.homedepot.com/p/DANCO-Un...702X/100344525 Unless I was looking in the wrong place I couldn't find anything like the one I was trying to replace.

Is it possible to just buy a premade one, like the one in the first picture, where I can just slip it on and tighten a screw? For the one I removed it had a single hex screw at the bottom to tighten and release. The Home Depot one had me lining up things, punching screws through plastic, and trying to screw things into place. I want an all in one solution.

The way the replacement I got had to be secured with a pointed screw (which is pointed to pierce the plastic) scratched the copper which got me worried that if I did any more I would end up cutting it and then I would be in a world of trouble. Also when trying to screw in the spout I heard a loud noise when trying to tighten it and the adapter piece came off the copper pipe. I am taking that thing back.

In the Delta line, the RP33794 adapter slips on to 1/2 inch copper, has a set screw.

These two include that adapter.
https://www.deltafaucet.com/parts-product-detail?modelNumber=RP5836 is a pull-down chrome finish diverter spout.

I think you would probably have to shorten your copper pipe.
https://www.deltafaucet.com/bathroom/product/RP73371BL is a more expensive pull-up diverter

EZ FLO sells slide on spout ($5 wholesale).
If your local HD doesn't have a thing like this, I'm sure you can buy one in other stores of or a plumbing supply outlet.

What you have is just a plain slip-on spout. WHat may complicate your life is the fitting on the pipe...it would depend on how recessed the thing is in the new one. SOme expect the pipe to be solid to the wall so the seal and fitting are too close, and it wouldn't slide all the way to the wall before hitting the fitting.

The alternative is to get a screw-on one. Delta makes a hybrid one where you solder on a fitting, then screw the new spout to the fitting. On that type, the seal is an O-ring (like the one you have).
