1. A connection assembly adapted for receipt of a male connection member at the interior of a grommet for operative attachment of retaining panel to a substructure, the connection assembly comprising:
a variable profile grommet of hollow unitary construction formed from elastomeric material comprising a first collar having a first effective diameter, a second collar disposed in spaced-apart relation from the first collar, the second collar being of substantially non-circular geometry defining a second effective diameter, the grommet further comprising a neck extending between the first collar and the second collar, and wherein an axial bore extends entirely through the grommet; a sleeve insert comprising a hollow stem extending from a point of insertion on one side of the grommet into the axial bore so as to at least partially line the axial bore, the stem comprising a proximal end and a distal end, the sleeve insert further comprising an annular flange extending radially outwardly away from the proximal end of the stem, the annular flange having a diameter greater than the axial bore at the point of insertion; and a retaining panel including a substantially non-circular access opening adapted to receive the second collar in pass-through relation when the second collar is aligned with the access opening, the access opening being further adapted to block the first collar against pass-through insertion, and wherein upon rotation of the grommet following insertion of the second collar, the grommet is blocked against withdrawal through the access opening and the retaining panel is held between the first collar and the second collar with the second collar disposed in partial surrounding relation to the access opening. |
