Connection of streamlined-section struts

A connection of a first streamlined-section strut with at least one second streamlined-section strut by using a connector,

• wherein the at least one second streamlined-section strut runs substantially orthogonally to the first streamlined-section strut,
• wherein the streamlined-section struts have a substantially rectangular base cross-section,
• wherein the at least one second streamlined-section strut has a mounting groove in at least one lateral surface and at least one edge flange,
• wherein said edge flange projects substantially orthogonally from an edge of the lateral surface outwardly of the lateral surface and outwardly beyond the substantially rectangular base cross-section of the at least one second streamlined-section strut to accommodate the connector substantially completely with said at least one edge flange, and projects toward the first streamlined-section strut at a predetermined distance and with a predetermined thickness,
• wherein the connector is securable to a front side of the first streamlined-section strut and also is securable to the lateral surface having the mounting groove of the at least one second streamlined-section strut,
• wherein dimensioning of the connector is essentially the same as the predetermined distance in an orthogonally running direction to the lateral surface;
• wherein for attachment of the connector to the lateral surface of the at least one second streamlined-section strut, an auxiliary element with at least one attachment shoulder projecting transversely over the cross section of the first streamlined-section strut can be attached, wherein the attachment shoulder can be inserted in the mounting groove and is securable in said mounting groove;
• and
• wherein the auxiliary element is attachable to the connector by means of the same attachment elements that also serve to attach the connector to the front side of the first streamline-section strut.
