I bought a 9-speed cassette online, and it came in like this:
The bag was ripped open too.
I tried to fit the two separate sprockets onto the cassette, but found no way.
Is this right?
The two loose cogs are inverted. Flip them over and try it again.
All cassettes have at least the two smallest cogs and the lockring as separate pieces.
I assume you bought this cassette on e-bay or from some on-line seller as it seems to be a "grey-market" part, i.e. resold from some manufacturer's overstock. Comercially packaged cassettes come in boxes and are assembled on a post or other retainer that keeps everything in order.
To install this cassette, place the grouped together cogs on the freehub body, then the larger of the two separate cogs with it's spacer side toward the larger ones, then the smallest cog, also with its spacer facing the others and then the lockring. You do realize thse cogs are "keyed" to the freehub body and the narrow spline on the body must be aligned with the narrow groove on the cogs?
I assume your freehub body is an 8/9/10-speed version. If it's a 7-speed body the cassette wil be too wide to fit.
The cogs don't actually fit together as one complete unit (like the old freewheels.) But once you put all the loose cogs on the hub they are made one by tightening the lockring.
I actually disassemble my cassettes on purpose to get 8 loose cogs. This makes it possible to clean everything more thouroughly.
Why "derailer" is the correct way to spell the gear-change mechanism: sheldonbrown.com/derailer.html

The last cogs always come appart i dont know whats the problem, And yo uare getting lucky because the miche ones come in individual spacers and cogs so probably that could make more than bad??? Just put the cluster in, put the other 2 in there, then the lockring, is that a problem???
The old 7 sp shimano HG came in 5 speed cluster and the last 2 plus the lockring just like the stuff u have in there, again, what is the big deal if the thing is new?
Correct, which is why I needed intelligent advice.or you have no idea how to put a cassette on.
Wrong, because I reputable seller would have sent it properly assembled and aligned. But, as HillRider pointed out, I bought from a gray market outfit.There is nothing wrong with the cassette in your picture.
Wrong again - what I needed was good advice, as provided by HillRider.I think you need a bike shop.
The smallest cog on this cassette is an 11 so you will need the special lockring made for the 11. I assume that is what you got.
Most lockrings have the recommended torque shown on the lockring in neuton-meters.
Note: the splines have 1 wider than the rest, and a narrow one right next to it.
line all the cogs up to that.
If you plan to do any of your maintenance work you'll need that tool and others. You do not have to have a torque wrench, just be sure to get it tight enough. A loose cassette can damage an aluminum freehub, poor shifting performance, and lots of noise.
Again, If you don't plan to tinker with the cassette yourself, run by a bike shop and they'll tighten the lock nut, maybe for a small fee, maybe for free.
I would buy the tool if i was you.
