Abstract

Self-sealing flexible tube connection for vacuum cleaners comprises a conventional body (1) with a rocker member (2) and a connecting piece (3). The connecting piece has an integral lip seal (7) interrupted by grooves (8) to improve its seating on the rocker member, against which the lip (9) is applied with prestressing.
