Down Pipe joints

[SALL2009]

I am planning on replacing a Hopper, 2 meters run of 68mm Down Pipe and attach a shoe at the end. I'm ok with fixing the items to the wall. But I don't know what I need to use at the joints i.e. top of pipe to hopper and bottom of the pipe to the shoe.
I have never done any such work outdoors (downpipes) so not sure what is used to seal the joints.

If they are a nice tight fit nothing,if they are not so tight fitting then a bit of clear silicone but never glue incase you ever need to remove for whatever reason,blockage etc.
