Patent Abstract

The invention relates to connectors for connecting tubular fiber-reinforced plastic composites with at least one component and tubular fiber-reinforced plastic composites in connection with a connector. The connectors and the tubular fiber-reinforced plastic composites are distinguished in particular by the fact that a form-fitting connection with a connector as a fitting in mixed construction design in the form of fiber-reinforced plastic composites with components is realized even for high pressures. For this purpose, a first end region of a tubular base body has an element for connecting the base body with the component as a connecting element. The second end region has, for connecting the base body with the tubular fiber-reinforced plastic composite, a thickening with groove-shaped recesses introduced at least in regions such that polygonal shapes or shapes of a conic section are defined by the recesses. Furthermore, at least one undercut is present in the base body between the connecting element and the thickening.
