Structural arrangement introduced into a sleeve connector having various cross sections for tubular metal posts

A sleeve connector having various cross-sections for joining tubular metal posts, the sleeve connector (100) comprising:

• one or more locking regions (120) provided with a ring of radially outwardly protruding and circumferentially spaced apart locking protuberances (121), wherein the locking protuberances (121) are formed prior to locking together ends of two tubular metal posts (300) with the sleeve connector (100) and have a maximum radial height (ht) that corresponds to 0.15 to 4% of the external diameter (D) of the respective locking region (120), said locking regions (120) being configured for locking together the ends of the tubular metal posts (300) by means of the mechanical deformation of the locking protuberances (121);
• a pair of conical centralization regions (110) at opposite ends of the sleeve connector (100), the one or more locking regions (120) disposed between the pair of centralization regions (110);
• and
• an abutment region (130) having one or more radially protruding and circumferentially arranged abutment protuberances (131) having a maximum radial height (he) that is different than the maximum height of the locking protuberances and that corresponds to a value between 30 and 80% of a wall thickness of the tubular metal posts (300).
