ABSTRACT:
A removable end plug for closing off the open end of a hollow vehicle bumper. The end plug comprises a molded unitary body of flexible deformable material having four side sections in the form of a hollow square and a four sided truncated pyramid shaped operator portion connected to one transverse edge of the side sections. The operator portion has a normal position whereat the truncated pyramid extends longitudinally away from the bumper opening and a reverse truncated pyramid position to cause said side sections to be bowed transversely outwardly and thereby substantially increase the force of engagement between the outer surfaces of said side sections and the four inside surfaces of the bumper to thereby lock the plug to the bumper.
