A T-link of two profile bars, with a link (1) comprising two elongate clamping jaws (6) which can be tightened transversely by a fixing element (5) and can be locked in position, closing like tongs, in undercut casing grooves (7) of a second profile bar (8), and which engage endwise in a cavity (3) in a first profile bar (4) and can be clamped onto cylindrically parallel inner webs (10) of a first profile bar (4) that are arranged between said clamping jaws. Improvement of the stability of the T-link is achieved in that the first profile bar (4) comprises more than two inner webs (10) evenly distributed about its inner circumference, in that tightened clamping jaws (6) exclusively clamp inner webs (10) with longitudinally linear and/or planar contact, and in that the clamping jaws (6) engage by each of their longitudinal edges (70) in a respective clearance (71) provided between the clamped inner web (10) and the inner web (10') adjacent thereto.

Assemblage en T de deux barreaux profilés, comprenant un raccord (1) présentant deux mâchoires de serrage longitudinales (6) serrées transversalement par un élément de fixation (5), pouvant être bloquées à la manière de pinces fermées dans des rainures génératrices (7) en contre-dépouille d'un deuxième barreau profilé (8) et s'engageant, à l'autre extrémité, dans un espace creux (3) d'un premier barreau profilé (4), lesdites mâchoires pouvant par ailleurs être bloquées sur des nervures internes (10) du premier barreau profilé (4) parallèles au tube et disposées entre elles. Afin d'améliorer la stabilité de l'assemblage en T, l'invention est caractérisée en ce que le premier barreau profilé (4) présente plus de deux nervures internes (10) réparties uniformément sur sa périphérie intérieure, en ce que les mâchoires serrées (6) bloquent exclusivement des nervures internes (10) appliquées linéairement et/ou en plan, et en ce que les mâchoires (6) s'engagent, par leurs arêtes longitudinales (70), respectivement, dans un espace intermédiaire (71) situé entre la nervure interne bloquée (10) et sa nervure interne voisine (10').
