Vibration dampers (124, 126) are located between the handle and the fastening mechanism to damp vibrations transmitted from the fastening mechanism to the handle. Limited rotation of the handle relative to the metal strip is possibly, but rotation beyond predetermined limits causes the fastening mechanism to tighten and/or loosen the metal strip on the housing.
