Abstract: A method for joining at least two components, in particular two sheet components of a vehicle body, by a flow-formed rivet sleeve is disclosed. The flow-formed rivet sleeve includes a cladding region, a first edge region, and a second edge region. A traction shaft including a base body and a head is introduced in the flow-formed rivet sleeve and the flow-formed rivet sleeve is inserted into respective through openings of the components. By a relative movement of the traction shaft to the flow-formed rivet sleeve, the flow-formed rivet sleeve is widened in the first edge region and is brought into contact with one of the components. The second edge region is bent towards the other component by a reshaping tool surrounding the traction shaft and is brought into contact with the other component.
