Have been published in the journal advice, how to repair vacuum cleaner hose with cut Velocimetry. But it does not work the necessary rigidity of the connection.

How to Unscrew a screw, which defies the screwdriver? I in these cases, apply the soldering iron: a few minutes of intense warm-up and the screw becomes obedient.
