Actually this has made me curious as to why it does slip with such a standard tightening mechanism. I\'ve just taken mine apart. The mechanism tightens by one half of a rosette pattern (connected to the tightening handle) squeezing onto another half (etched into the plastic head case) through a rubber washer. The fly in the ointment seems to be the inclusion of a steel washer in between the tightening handle rosette and the rubber washer, causing it to slip at the rubber/steel washer interface. Take out the washer, and both rosette patterns are only sepparated by the soft rubber washer - it doesnt slip with much less tightening as well.
