摘要：
A tube has a cuff to be inserted over a tubular connector having a cylindrical exterior surface. The cuff has an annular bead provided on an internal diameter that is smaller than an external diameter of the tubular connector. The annular bead is structured to resiliently deform upon engagement with the cylindrical exterior surface so as to provide a gas tight seal and retain the cuff on the connector, and the bead has an axial width that is less than a maximum insertion distance of the cuff.
