There should be a screw to hold the element
in place. Image of 182A 1 pc. elements: http://tinyurl.com/pvkoum6
The screw doesn't have to be super tight; the outer metal
of the heating element(s) is relatively thin. It may
be that there is a dimple at the element for screw to seat in.

On that note, i recall reading of someone
shimming the element so it would contact the tube as
much as possible. But then the
internet is full of "information". IIRC, I hammered
a piece of brass flat and shimmed the element at the screw side
of tube.
I doubt doing this helped improve cooling though.
