    • The invention relates to a joint comprising two tool sections (3, 5), each having a respective flat surface (47, 49). One of said sections contains a cavity (9) and the other section a lug (7) that can be at least partially inserted into the cavity (9). The joint also comprises a tensioning unit (19) for generating a tensioning force, which can be used to press the flat surfaces (47, 49) of the tool sections (3, 5) against one another in a pre-stressed condition, said tensioning unit (19) comprising an actuating device (21) and at least two tensioning bodies (43), which are housed in the interior of the lug (7) so that they can be displaced in the axial and radial directions of the joint (1) and which when pre-stressed act on an inner tensioning shoulder (15) of the lug (7). In the interior of the lug (7), the tensioning unit (19) comprises a piston (23), which can be displaced in the longitudinal direction of the joint (1) and which can be coupled to the actuating device (21) by means of a coupling unit (27, 29, 31) in such a way that in a first functional position of the actuating device (21), said piston adopts a tensioning position and in a second functional position of the actuating device (21) adopts a release position. The joint is characterised in that the actuating device (21) comprises at least one rotatable actuating element (25), whose rotational axis can be rotated about an angle of preferably 90° to the longitudinal axis (17) of said joint (1) and has an eccentric outer surface, which co-operates with the coupling unit in such a way that a rotation of the actuating element (25) causes an axial displacement of the piston (23).
    • 它是一种联合具有两个各自的平坦表面(47,49)的一部分的工具(3,5),其中之一具有凹部(9)和一个至少部分地进入所述凹部(9)插入中空的凸台(7),和 用夹紧装置(19),用于产生一个夹紧力与在它们的平坦面(47,49)的区域中的夹紧状态的工具部件(3,5)的每一个按压时,所述张紧装置(19)的致动器(21)和至少两个 包括夹持体(43),其(1)可移动地容纳在轴向和接头的径向方向上的投影(7)的内部,并在夹紧状态上的突起的内夹紧肩(15)(7)动作,并且其中所述张紧装置( 19)A(布置在所述接头(1)可移动的活塞的纵向方向上的投影7)的内部(23),它通过一个耦合装置(27,29,31)与所述Betätigungseinri 矩形(21)是如此地联接,它被布置在其夹持位置的致动装置(21)的第一功能位置,并且在其释放位置的致动装置(21)的第二操作位置,提出了。 这是其特征在于,所述致动装置(21)包括至少一个可旋转的致动器元件(25),其旋转轴线在优选为90℃到接头的纵向轴线(17)的角度(1)是可旋转的并且具有带有偏心外表面 所述耦合装置协作,使得所述致动元件(25)的旋转引起所述活塞(23)的轴向移动。
