Wrap the outside of the tube (with the ribs for screwing on the nozzle) exactly where you need to screw on the nozzle, wrap it a few times to make sure you get the entire ribbed part (don't get mad and do it thick) just enough to cover it, tear off the end, screw back the nozzle. Lots of instructions for a very simple application. No household should have a role like this for leaks, spares, etc. And depending on how old your attachments are, you may need a good wrench to remove them. In this case, don't rip off the whole pipe, just hold on to it while you struggle. Once removed, clean with CLR and a wire brush before reinstalling. Remove rust and watery lime. Soak them if necessary, it won't hurt. THEN use tape to reattach it. This is a clip that can be kept under the kitchen sink or in the trash drawer. In the end you always need it.
