ABSTRACT:
The invention relates to a medical or dental-medical treatment which at its rearward end has a coupling element for coupling on to a matching coupling element of a flexible supply line, and in its forward region has a holder device for a tool, the handpiece being of a rearward and a forward handpiece section which are connected with one another by means of a plug-in connection and are fixed on one another by means of a latching device which has a latching arm extending approximately axis-parallel and which is transversely elastically bendable, which latching arm is arranged on the one plug-in connection part and is latched in its free end region with a latching element arranged on the other plug-in connection part . For the purpose of improving the connection between the rearward and the forward handpiece section the latching device at the same time axially fixes an insert part of the handpiece, which insert part sits in a plug-in recess of the one and/or of the other plug-in connection part.
