    Abstract: The device connects a first end-coupler with a second end-coupler, in particular of a piping. A nut is provided with a threaded bore in which the first end-coupler is screwed along a longitudinal axis. In a tightening position, the first end-coupler is in axial stress with a second end-coupler accommodated in the nut. Anti-rotation means are provided between the nut and at least one 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 made in the material of the nut to lockingly interfere with substantially planar faces formed on the second end-coupler.

    Abstract: A nut for securing first and second pipe end-pieces together includes a nut lock having a stop member secured to the nut body, and a second element which is rotatable inside the nut body and having a locking feature adapted to lock onto a corresponding locking structure of the second end-piece. The stop member and the second element include corresponding face teeth which are urged to intermesh by an axial compression spring. At or near the tightened condition of the assembly, the second element is locked onto the second end-piece so that rotation of the nut is possible only if the torque applied exceeds a given threshold, for which the face teeth jump over each other while the spring is alternately stressed. A compact design is obtained with the lock positioned at the rear of the nut thread. The clamping face is axially between the nut thread and the lock.
