ABSTRACT:
A coupling, arranged to form a frictional joint between two mechanical elements, comprising of a tubular contact member, arranged to take up a non-deformative frictional contact with an element to be attached by means of a first peripherical surface when a mainly plane spring ring, extending from the opposed peripherical surface mainly perpedicularly to the length axis of the element to be attached, is twisted or tilted by means of a manually operated force applying member to an inclined relationship to said length axis, said tubular contact member having a longitudinal section causing the applied force from the spring ring to be equally distributed over the contact surface with the element to be attached.
