A bellows with respective cylindrical ends is sealingly secured within the cylindrical end portions of the tubular connectors, which are also formed with spherically shaped portions fitting one within the other outside the bellows. A spherically shaped load transmitting sleeve is connected to two pairs of diametrically opposed pivots at right angles to each other, with one pair of pivots connecting the sleeve and the outer spherically shaped connector portion, and the other pair of pivots connecting the sleeve and the inner spherically shaped connector portion.
