Abstract
Described herein is a medical or dental handpiece head having a head sleeve detachably connected by a screw or threaded connection to a closing cap, and a locking device for locking the closing cap with the head sleeve. The locking device between the closing cap and the head sleeve is formed by at least one spring element. The locking device is designed and arranged so that unintentional release of the screw connection between the closing cap and the head sleeve caused by vibrations during operation of the handpiece can be suppressed.
