Abstract
A one-piece rubber plug () includes a main body () with insertion holes () and tubular projections () communicating with the insertion holes () and projecting from the rear surface of the main body (). Restricting surfaces () matchable with restriction areas () on the outer peripheries of the tubular projections () are formed on through holes () of a rear holder (). The rear holder () is displaced between a deformation permitting position where the restricting surfaces () are not in contact with the restriction areas () and where resilient radially expansive deformations of the tubular projections () are permitted and a deformation preventing position where radially expansive deformations of the tubular projections () are prevented by bringing the restricting surfaces () into contact with the restriction areas () substantially over the entire circumferences.
