Abstract
In a hand held piece for dental or surgical use comprising a resilient clamp () for holding the cylindrical shank () of a tool, the height of the head () of the piece can be reduced owing to an inverted arrangement of the clamp in relation to the arrangement of the prior art. The clamp is slideably mounted in a hollow shaft (), its flexible jaws () being directed forwards to enter into contact with a loosening sleeve () fixed in a front end of the shaft, i.e. on the tool side. The clamp is longitudinally connected to a pusher () manually activated by the operator for opening the clamp. A snap fit device () offers a higher initial resistance to movement of the clamp than the standard minimum axial pull force of the tool.
