WHAT IS CLAIMED IS:

1. An ultrasonic assembly comprising a transducer (2) and a sonotrode (4) characterized in that the sonotrode (4) is annular and has an adapter portion (15) disposed between the transducer (2) and the sonotrode, the adapter portion being in the form of a projection (16) projecting from the sonotrode (4) and displaying, at its end facing away from the sonotrode, an anchorage device (14) for direct or indirect connection to the transducer (2).

2. The assembly as claimed in Claim 1, characterized in that the adapter portion (15) extends radially outwards in relation to the geometric centre of the sonotrode (4).

3. The assembly as claimed in one or more of Claims 1 to 2, characterized in that the projection (16) is symmetrically designed in relation to a radius extending through the sonotrode (4), but displays varying cross sectional configuration along said radius.

4. The assembly as claimed in one or more of Claims 1 to 3, characterized in that the projection (16) has a region of greater cross sectional area and a region of smaller cross sectional area, the latter region being located more proximal the geometric centre of the sonotrode (4) than the former region.

5. The assembly as claimed in one or more of Claims 1 to 4, characterized in that the projection (16) has a region adjacent the annular portion of the sonotrode (4) of reduced cross sectional area.

6. The assembly as claimed in one or more of the preceding Claims, characterized in that the projection (16) is connected to the annular portion of the sonotrode (4) via a waist (17).

7. The assembly as claimed in one or more of the preceding Claims, characterized in that the anchorage device (14) displays means for configurationally stable engagement with adjacent assembly parts.

8. The assembly as claimed in Claim 7, characterized in that the anchorage device (14) includes a thread (19) for releasable interconnection with adjacent assembly parts.

9. The assembly as claimed in one or more of the preceding Claims, characterized in that the adapter portion (15) is of one piece manufacture with the sonotrode (4).

10. The assembly as claimed in one or more of the preceding Claims, characterized in that a booster (3) is disposed between the transducer (2) and the sonotrode (4), the adapter portion (15) being mechanically connected to the end of the booster (3) facing away from the transducer (2).
