Abstract
In order to provide a torque-transmitting joint comprising a tube of fiber-reinforced plastic material and a metallic inner sleeve which has a knurled outer surface, the inner sleeve is pressed into retaining regions of the tube having reinforcing fibers extending substantially entirely in the circumferential direction, whereby the knurling produces a counter-knurling because of the visco-elastic deformation of the material of the retaining regions.
