It is characterized in that the trenching bodies (10a, 10b) are connected by at least one adapter (15), which comprises a bearing surface (16) and two insert profiles (17a, 17b), which are arranged on both sides of the bearing surface (16) and are connected thereto, wherein the bearing surface (16) is arranged between the bearing base plate (11, 12) and the insert profiles (17a, 17b) are inserted into two concentrically arranged column openings (14) of the bearing base plates (11, 12).
