ABSTRACT:
A jointing device primarily for scaffold or stand system, for example in exhibition show cases and the like, which system is assembled of tubes (3). The jointing device is a junction, to which one or several tubes (3) are attached, where each tube has one end to co-operate with the jointing device. A pull rod (5) comprising a T-shaped end portion (6) is provided in each tube and cooperates with a preferably substantially spherical junction member (1). The jointing device has a substantially sleeve-shaped attachment member (34) inserted within the tube (3) comprising 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.
