The invention relates to a pipe joint for joining a tubular component (1) to a receiving piece (2), the pipe joint comprising a fitting body (3) having a recess (8), a tightening nut (6a) having a first thread (7a), the fitting body having a corresponding thread (4), and a cutting ring (9) being arranged to be pressed between a wedge-like wall portion (10) of the recess, and the tubular component when the tightening nut is tightened. In order that the pipe joint could be tightened to form a leak-proof and strong joint using low torque, which enables the use of small tools applicable in confined spaces, the pipe joint comprises a supplementary nut (6b) having a thread (7c) whose handedness corresponds to that of the first thread (7a) but is smaller, the tightening nut comprising a second thread (7b) corresponding to that of the supplementary nut.
L'invention concerne un joint de tuyaux conçu pour raccorder un composant tubulaire (1) à une pièce de réception (2), qui comporte un corps de fixation (3) pourvu d'un évidement (8), un écrou de serrage (6a) pourvu d'un premier filet (7a), le corps de fixation présentant un filet correspondant (4), et un anneau de coupe (9) disposé de manière à être pressé entre une partie paroi en forme de coin (10) de l'évidement et le composant tubulaire lorsque l'on serre l'écrou de serrage. Afin que l'on puisse serrer le joint de tuyaux de manière à former un raccord étanche et solide utilisant un faible couple, ce qui permet d'utiliser de petits outils dans des espaces clos, le joint de tuyaux comporte un écrou supplémentaire (6b) pourvu d'un filet (7c) dont la chiralité correspond à celle du premier filet (7a) tout en étant plus petite. L'écrou de serrage comporte un second filet (7b) correspondant à celui de l'écrou supplémentaire.
