Thank youIt is the "octave vent tube" and all saxes have them in various lengths. Sax swabs that have a brush in the center are notorious for getting stuck there. If you use a swab that is all cloth, the key is to not let it get bunched up when you pull it through. I use and recommend the HW Padsavers which don't present a problem.

Thank YouYes, it is supposed to be there.
Its ostensible purpose is to keep spit out of the octave hole, but its true purpose is to get your swab caught up.
This is proof that saxophone manufacturers do have a sense of humour.
My solution is to use a padsaver-type swab.
Actually, yet another purpose is to make techs have a b#tch of a time getting their dent rod past it.Its ostensible purpose is to keep spit out of the octave hole, but its true purpose is to get your swab caught up.
In truth....dunno what your tech replied exactly...but I do this pretty often. Never has resulted in any ill effect whatsoever.I asked him about the usefulness of the very same thing you're asking about, and if it could be sawed off...
Maybe by some sort of coincidence I just turned purple with yellow dots for a few seconds or something, but I clearly felt - at the way he looked at me for a moment - that I had said something wrong. After a few explanations we laughed it off.
Going back to the original problem - laying the cloth out carefully inside the bell before pulling the cord GENTLY out through the neck socket, I have NEVER had a cloth catch on that internal pip tube.
