Arrangement and method for sealing and locking a dividable coupling (14) between a first duct part (15) and a second duct part (16), where said duct parts (15, 16) are adapted for coaxially overlapping engagement with one another in an engagement zone (31) within which a hollow locking and sealing zone (26), which can be expanded radially by means of pressurized fluid, is arranged on said first duct part (15) for sealing and axially locking engagement with an opposite recess (38, 48) running all the way round in said second duct part (16). The invention is characterized in particular in that a guide zone (32) is present on one (15) of the duct parts adjacent to said engagement zone (31), which guide zone (32) has a radially inwardly inclined guide surface (33) adapted for guiding the opposite duct part (16) into said coaxially overlapping engagement. |
