The backing plate member comprising a substantially planar member made of a resilient material and having a cut-out portion and substantially conforming in shape to the shape of the end portion of the tube enabling passage of the end portion through the cut-out portion of the planar member, a first ramped surface being formed on an edge portion of each of the opposing projections and adapted to enable each projection of the tube to be rotated in a given direction onto the surface of the planar member thereby locking the tube with respect to the planar member.
