    Abstract: The device connects a first end-coupler (1) with a second end-coupler (2), in particular of a piping. A nut (15) is provided with a threaded bore (17) in which the first end-coupler (1) is screwed along a longitudinal axis (X). In a tightening position, the first end-coupler (1) is in axial stress with a second end-coupler (2) accommodated in the nut. Anti-rotation means are provided between the nut (15, 115) and at least one (2) of the end-couplers to prevent relative rotation except when a torque exceeding a predetermined threshold is applied thereto. The anti-rotation means consist of at least one tab (21) made in the material of the nut (15) to lockingly interfere with substantially planar faces formed on the second end-coupler (2).

    Abstract translation: 该装置将第一端部联接器(1)与第二端部联接器(2),特别是管道连接。 螺母(15)设置有螺纹孔(17),其中第一端部联接器(1)沿着纵向轴线(X)旋拧。 在紧固位置,第一端部联接器(1)处于轴向应力,并且第二端部联接器(2)容纳在螺母中。 在螺母(15,115)和至少一个(2)端部联接器之间提供防旋转装置,以防止相对旋转,除非超过预定阈值的转矩被施加到其上。 防旋转装置由在螺母(15)的材料中制成的至少一个突片(21)组成,以与第二端部联结器(2)上形成的基本平坦的表面锁定地干涉。
