The invention relates to a method for fixing a plurality of workpieces (12, 14) by means of a hollow rivet element (18) with an open setting end (24) and a closed closing end (26), comprising the following steps: a) passing the rivet element (18) through mutually aligned openings (16) of the workpieces (12, 14), b) introducing a fluid, in particular air, under high pressure from the setting end (24) of the rivet element (18) in a hollow space (29) of the rivet element (18), and c) plastically deforming and setting of the rivet element (18) by the fluid at the closed closing end (26) of the rivet element (18). 本发明涉及种用于借助空心铆接元件(18)固定多个工件(12、14)的方法，所述铆接元件包括敞口的安置端部(24)和封闭的封闭端部(26)，该方法具有如下步骤：a)将铆接元件(18)引导通过工件(12、14)的相互对齐的开口(16)，b)将流体、尤其是空气在高压下从铆接元件(18)的安置端部(24)导入铆接元件(18)的空腔(29)中，并且c)通过流体在铆接元件(18)的封闭的封闭端部(26)上使铆接元件(18)塑性变形和安置该铆接元件。
