A flexible tube portion for an irrigation line connected to a supply of fluid for surgical or dental use is disclosed, wherein the flexible tube portion cooperates with rollers of a peristaltic pump for distributing fluid, which includes a particular structure which, between two free ends thereof, define a distance, which, combined with the length of the tube portion, gives the tube portion a determined profile enabling its positioning directly underneath the raceway of the rollers of the pump. Also disclosed is a peristaltic pump including a plurality of rollers that roll over a flexible tube portion of an irrigation line connected to a supply of fluid for surgical or dental use, which includes a certain structure for receiving the flexible tube portion in front of the plane in which the rollers move, then bringing the flexible tube portion underneath the rollers, and pressing the tube portion against the rollers.

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.
