<p>The connector (10) has two opposite parts (12, 14) comprising two portions (16, 18) adapted to end portions of a pair of transverse tubes (11, 13), and a longitudinal tube (15), respectively. The portions are integrated with each other. A screw (22) and a nut maintain the opposite parts to block the transverse tubes relative to the longitudinal tube. The portions interfere with each other by a fitment (20) to prevent separation of the portions in a direction perpendicular to a plane in which the tubes are projected.</p> |
