Pivotable roll-bar

The bar has a lock (32) with which a swiveling tube (22) is deformed in a working position against a connecting element (30). A stand tube (24) is material-conclusively connected at welding surfaces (SF). A swiveling joint (31) has a swiveling axis around which the swiveling tube is tiltable. The connecting element has two plates (33, 34) that are symmetrical to each other. A stopping surface (AF) and the welding surfaces are designed as edge profiles (35) of the plates, where the welding surfaces are aligned in a horizontal manner.
