Well, you can see that this code is much bigger than mine. I'm a bit
uncomfortable because I don't have yet the lilypond-scheme vocabulary to
understand it.
OTOH, it has a more convenient syntax, not needing to add a \glissando
in every note. It should be a good solution for longer passages. I'm
saving it for future use ;)

Hi Caio,
How about:

I think I got it. It's a bit of an ugly code, but works.
\version "2.19.35"
\relative c' {
\override NoteHead.stencil = #ly:text-interface::print
\override NoteHead.text = \markup { \null }
\override NoteHead.stem-attachment = #'(0 . 0)
\override Glissando.thickness = #5
\override Glissando.bound-details.left.padding = #0
\override Glissando.bound-details.right.padding = #0
e8[\glissando g\glissando b\glissando g\glissando e\glissando
d'\glissando e,]
}
