I have a Dyson Small Ball Allergy corded upright vacuum cleaner.
I want to buy the up-top tool ,https://www.dyson.co.uk/support/journey/tools/917646-01.
Will the up-top tool fit my model? It is not clear (to me) from the pictures and descriptions whether it will lock into the end of the hose.
Hey 
It’s a little confusing isn’t it! Your model isn’t shown under the compatible section.
My inquisitive mind wanted to look at the model and the accessories associated with it. Looking at it that way, it shows it is compatible. Small Ball Accessories..
If you wanted to double check, just message their WhatsApp service. Part number shown above.

Hey!
If you wanted to take a gamble, online purchases are subject to distant selling regulations. This is where you’d get a return and refund, even once opened.
I’d certainly take the risk for £25.
