ABSTRACT:
The tensioning mechanism (18) comprises a clamp bolt (28), arranged in a displaceable manner in a transverse bore (26) in the fitting plug (12) and two diametrically opposed retainers (34, 36) in the second component (14) which engage with an axially facing internal or external cone against a complementary internal or external cone on the clamp bolt (28) and, during tensioning, are tensioned with the same in a wedge fashion. According to the invention, the clamp bolt (28) comprises a frustum-shaped external cone (40), the base diameter of which is smaller than the diameter of the guide surface (62) thereof in the transverse bore (26).
