ABSTRACT:
A main member of soft plastic material and a second member of hard plastic material, chemically compatible and thermally bonded together. The second member is partially slitted having a ring element embedded in the main member, and segments distributed circumferentially around the ring. The segments can be swung radially to facilitate insertion into a hole, and they spring outwardly to grip the panel in which the grommet is mounted. In one form the second member is entirely slitted, and thereby made up of separate segments or fingers.
