Abstract: Process for connecting and assembling tubular elements, according to which the various tubes (1) are joined to one another by connectors or sleeves (2), the ends (10-3) of these two elements being fitted one inside the other and the bond being obtained by adhesive bonding.The process is distinguished by the fact that, after fitting the two members one inside the other and before the adhesive has set, an additional connector (4) is introduced inside one of the elements, one part (5) of the additional connector being pressed against the inside of the surface (8) of the element inside which it has been introduced, and the other part (6) of the additional connector being screwed inside the second element, the final setting of the adhesive taking place after installation of this additional joining element.

Abstract: A tubular material based on a fabric reinforced resin, said material comprising layed up fabric layers, the inside and outside layers consisting of bidirectional braided sheaths, said latter two layers sandwiching an intermediate, unidirectional braid consisting primarily of parallel, longitudinal yarns at least 10% of which have a high tensile strength and the remainder of which are yarns of the same type as the yarns of said bidirectional braids. An application in the construction of a bicycle frame is described.
