A lockable friction joint, in particular one intended to be set to a desired relative swing position between two sections of tube, whereby the friction joint comprises a first joint part with a first arm part or section of tube and a second joint part with a second arm part or section of tube. The first joint part and the second joint part each support a ring provided with a pusher dog. The friction joint comprises two friction disks provided with holes, each disk having means for transferring motion to the rings. A friction plate, provided with a hole, is arranged between the friction disks. The friction disks are coupled to transfer motion with the ring that is located on the opposite side of the friction plate, and the friction joint is compressed by adjustable tightening means. |
