In case of failure of the damping element due to damage or fatigue of the damping material is prevented by the undercut that the grip element can be separated from the fastener. The grip element is thus secured by the undercut against tearing. Also, the handle member is secured by the undercut against overuse because the undercut limits the deflection of the handle member relative to the fastener.
