A method of attaching an artificial tendon (1) at a support device having a supporting material (2), the artificial tendon is provided for flexing or extending a joint (3) by means of pulling the tendon, stitching (5) across the tendon with a low friction thread, forming a tunnel (12) for the tendon between the supporting material and the stitching, in which the tendon may travel. A tunnel for an artificial tendon to be able to travel in, positioned at a surface of a supporting material of a supporting device, formed by the supporting material and a stitching across the tendon, the stitching comprising a low friction thread. A strengthening glove having artificial tendons for flexing or extending at least one finger, characterised in that the tendons run in a tunnel formed by the supporting material and a stitching across the tendon.
