Abstract: A handle assembly and method of assembling a grip handle to a vehicle. The handle assembly includes two base unit and each include a primary and auxiliary projection that are press fit into an opening formed in a structural part of a vehicle. Detents are provided on the projection and configured to be assembled to a vehicle with a minimum force and require a removal force that is substantially greater then the force of insertion. A method of assembling the assist grip handle to a vehicle can be accomplished by inserting molded projections into holes formed in a structural vehicle body panel. The projections include detents that are compressed as the projections are inserted into the holes and are expanded after the projections are fully inserted into the holes.
