<p>A jointing device primarily for scaffold or stand system, for example in exhibition show cases and the like, which system is intended to be assembled of tubes (3), which jointing device is intended to be a junction, to which one or several tubes (3) are intended to be attached, where each tube is intended with one end to co-operate with the jointing device, and means are provided intended to be inserted in a tube at one end thereof and be fastened in the tube, and a pull rod (5) comprising a T-shaped end portion (6) is provided intended to co-operate with a preferably substantially spherical junction member (1) arranged to constitute a hold for the pull rod and holder-on, and to be fixed at the tube, which junction member is arranged for co-operation with more than one pull rod. The jointing device is especially characterized in that a substantially sleeve-shaped attachment member (34) intended to be inserted into a tube (3) comprises inner stop members (35) for co-operation with stop members (36) located at the pull rod (5), so that the pull rod without axial displacement is rotatable about the axial direction in relation to the sleeve (34) in a predetermined direction, but substantially not in the opposite direction.</p> |
