<p>Connecting piece (1) including a rear section with an W-shaped cross section comprising longitudinal grooves (30) with a C-shaped longitudinal section, where the wire bars (Vt1, Vt2) of the relevant adjacent cable channelling sections (B, B) are fitted; a central portion (31) that connects the respective longitudinal grooves; and a series of flanges (32) extending from the outer edges of the grooves (30) that are overlapped at the peripheral area of such wire crossbars of the relevant cable channelling section. Such connecting piece (1) which generally has the shape of a U, has a central branch (10) that practically covers the whole length of the respective central branch (Vt1) of the cross wire bars, and side branches (11) that form an angle with the central branch (10) which is equal to, or greater than the angle formed by the side branches (Vt2) and the central branch (Vt1) of the cross wire bars, and each one of the side branches (11), fully or partially covers the respective side branch (Vt2) of the cross wire bars; furthermore, the length of the flanges (32) corresponding to the side branches (11) is equal to or smaller than the cross distance between the adjacent longitudinal wire bars (V1), and such flanges comprise a lower bevel edge (320) inclined downwards, to house and retain such longitudinal wire bars (V1) .</p> |
