The invention elates to a device (20) for connecting hollow organs (24, 25), which device comprises various elements that are held by holding devices. Said holding devices can be laterally displaced on a slide rail (21), rotated or detached and put on and their position can be secured if required. The traverse (31) is used as a stop for the axial alignment of the holding devices. The two holding devices (22, 23) carry clamping devices for retaining and, if required, clamping off the hollow organ ends (24, 25). The holding devices (26, 27) carry fittings (10, 11). The two hollow organ ends (24, 25) to be connected are pushed through the fittings to such an extent as to project over the fitting ends by a defined extent. The ends of the hollow organs are then turned up by the ends of the fittings using two turn-up devices (28, 29). The holding device (30) in the center holds an additional fitting (14) into which the two fittings (10, 11) are inserted with the turned-up hollow organ ends and secured.
