Abstract: An elongated two-piece expandable sealing plug (20) that is adapted to sealingly close a marginal end portion of a hole or opening (22) provided in a body (21) broadly comprises: a cup-shaped member (23) having an annular open upper end, having an outer surface that is adapted to face toward a wall on the body surrounding the opening, and having an inner surface (38) that diverges radially outwardly in a direction toward the member upper end; and a head having an outer rim portion (25) mounted on the upper end marginal end portion of the member for rotation therewith, and having a central portion (26) arranged within, and secured to, the rim portion; wherein the member is adapted to be inserted (i.e., slidably and/or rotatively) into a marginal end portion of the body opening (Fig. 2); and wherein the central portion is adapted to be forcibly pushed toward the bottom of the cup-shaped member to (a) cause the central portion to physically separate from the rim portion, and (b) cause such separated central portion to movably engage the inner surface of the member to urge the member outer surface to move radially outwardly into engagement with the walls of the body about the opening (Fig. 4).
