Date Oct. 13, 1983.In order to guarantee the sealing quality of a joining between a pipe socket and a tube by means of a clamp pressing a tube on a pipe wall, where the press-on power to be exercised by the tube clamp will act as uniformly as possible all over the total pipe circumference and cause no damage to the tube, it is suggested that the clamp is an open tube clamp being operative by its inner clamping power over a relatively wide-ranged press-on surface, being moved into its acting position by a tool overcoming the clamping power, and where an almost uniform pressing is provided extending over the total press-on surface (F) by a cross section increasing from the open ends (E1, E2) in direction to the clamping dead center (R). Thereby the change of the cross section of the part exercising the pressing-on is essentially accomplished by at least one open clamping ring tapering from the clamping dead center (R) in direction to both sides according to the required measure of forces, where the clamping ring is designed in such a manner that in its dimensions it is outwards exceeding the part defining the mere press-on surface (F). |
