A tubing section coupling comprises a first tubular portion and a second tubular portion (18,20) having an external surface adapted to slidingly engage an internal surface defined by the first tubular portion. The first and second tubular portions (18, 20) are axially restrained by means of a fixing device adapted to releasably connect the first and second tubular portions together. The first and second tubular portions (18, 20) each define a profile; the profiles are adapted to be connected to rotationally restrain the tubular portions.
L'invention porte sur un raccord de section de tubage qui comprend une première partie tubulaire et une seconde partie tubulaire (18, 20) ayant une surface externe apte à s'engager de façon coulissante avec une surface interne définie par la première partie tubulaire. Les première et seconde parties tubulaires (18, 20) sont axialement retenues au moyen d'un dispositif de fixation apte à relier ensemble de façon libérable les première et seconde parties tubulaires. Les première et seconde parties tubulaires (18, 20) définissent chacune un profil ; les profils sont aptes à être reliés pour retenir en rotation les parties tubulaires.
