Abstract

The invention relates to a clamping element (1a; 1b; 1c; 1d; 1e) for a clamping device for fixing a tube to be flanged, comprising at least one receptacle (3), which is curved around an axis (2), for a tube to be flanged, wherein at least one wall (4) of the receptacle (3) has at least one clamping portion (5) which is brought into an active position against the tube in order to clamp the tube against a counter‑portion. It is provided that the clamping portion (5) is formed by at least one material elevation (6.1, 6.2; 7.1, 7.2) which circulates at least partially over the periphery of the receptacle (3) substantially without displacement in the direction of the axis (2). In addition or as an alternative, positive engagement means (20) are provided which can be brought into an active position against positive engagement means of another or further clamping element in order to form a positive locking of the clamping elements against one another which acts in the direction of a flanging force (FB). The invention also relates to a clamping device for fixing a tube to be flanged. The invention further relates to a flanging device (200) for flanging tubes, in particular tube ends.
