ABSTRACT:
A closure for a tube is a two piece stopper. The inner piece extends into the tube and the outer piece engages the exterior of the tube's sidewall. The outer piece has an inwardly extending shoulder which supports a projection of the inner piece. The two pieces are held together by a C-shaped washer that rests above the inner piece and in a channel formed in the outer piece.
