Abstract
Joint body is of weather-resistant material, can yield elastically and is delimited by a segment of a conical lining coinciding with the mid-axis of the bulb. The segment's annular edges are lines of inter-section of the conical lining with pref. 2 other conical lining(s) whose generatrices form angles with the symmetry axis, the limiting value of >=1 of these angles being approx. 180 degrees.
