A turnbuckle (10) is made by a method including preparing an iron tube (40) having a longitudinal through-hole (42). A diameter of each of two ends (50) of the iron tube (40) is reduced to form a coupling section (12) having an engaging hole (121), with an interconnecting section (11) interconnected between the coupling sections (12). The interconnecting section (11) is punched in a direction perpendicular to the longitudinal through-hole (12) to form a transverse through-hole (13) perpendicular to the longitudinal through-hole (42) and between the coupling sections (12), leaving two opposite peripheral wall portions (44) spaced by the transverse through-hole (13) and forming a bend (14) extending inward from each of two end edges (46) of each peripheral wall portion (44) into the longitudinal through-hole (42). An abutting portion (15) is formed between each bend (14) and one of the end edges (46) of one of the peripheral wall portions (44). Inner threading is formed in the engaging hole (121) of each coupling section (12).
Fabrication d'un tendeur (10) par une méthode consistant à préparer un tube de fer (40) ayant un trou traversant longitudinal (42). Un diamètre de chacune des deux extrémités (50) du tube de fer (40) est réduit pour former une section de couplage (12) muni d'un trou d'engagement (121), avec une section d'interconnexion (11) entre les sections de couplage (12). La section d'interconnexion (11) est perforée dans un sens perpendiculaire au trou traversant longitudinal (12) pour former un trou traversant transversal (13) perpendiculaire au trou traversant longitudinal (42) et entre les sections de couplage (12), laissant deux parties opposées des murs périphériques (44) espacées par le trou traversant transversal (13) et formant une courbe (14) s'étendant vers l'intérieur à partir de chacun des deux bouts (46) de chaque partie de mur périphérique (44) dans le tou traversant longitudinal (42). Une partie adjacente (15) est formée entre chaque courbe (14) et un des bouts d'extrémité (46) de l'une des parties de mur périphérique (44). Un filetage interne est formé dans le trou d'engagement (121) de chaque section de couplage (12).
