The reception member is provided with two generally semicylindrical shells connected to each other through a thin-walled hinge portion and adapted to form one cylindrical shape upon being closed onto each other along the matched edges thereof and a plurality of resilient engaging pieces regularly spaced in the longitudinal direction on the inner wall of each of the shells.
