Zusammenfassung:	A one-piece spacer tube for receiving a fastener includes a tubular wall defining a central bore therebetween and a plurality of guiding indents integrally formed in the wall. The indents are arranged in pairs that are longitudinally spaced along the length of the wall. The guiding indents include guiding surfaces that project radially inwardly into the central bore to guide a fastener extending through the central bore. Un tube d'espacement monopièce servant à recevoir un dispositif de fixation comprend une paroi tubulaire définissant un trou central entre eux et une pluralité de crans de guidage formés intégralement dans la paroi. Les crans sont disposés par paires qui sont espacées longitudinalement sur la longueur de la paroi. Les crans de guidage comprennent des surfaces de guidage qui se projettent radialement vers lintérieur dans le trou central pour guider un dispositif de fixation se prolongeant dans le trou central.
