Abstract
Abstract A grommet comprises a pair of mating telescoping halves with each half comprising a tubular body and a flange extending radially outward therefrom. The body of one half is disposed over and about the body of the other half. The flange on one half is spaced from the flange on the other half. The inner surfaces of the outer body includes a radially inwardly extending projection and the outer surface of the inner body includes at least one recess receiving the projection for securing one half relative to the other to form the grommet.
