Abstract

A connection between a building component in the form of a pipe, a mounting part, a housing or the like and a pipe-shaped line element of metal. The building component has an essentially radially extending, ring-shaped contact surface, against which a ring-shaped collar arranged on the line element is tensioned by fastening means that grip behind the collar. In the region between its inside and outside diameter, the collar has at least one axial thickening that extends ring-shaped around the axis for the line element, and that the thickening is produced by axially compressing at least one radially outward extending and at least one radially inward extending annular undulation, arranged adjacent in axial direction, of the wall that forms the collar.
