    摘要: A metal frame is provided with at least one first section bar (4; 25) having an end portion, which defines a first coupling portion (7; 29), and is delimited by two first side walls (8; 30) which are substantially parallel to one another, and with at least one second section bar (2; 23) having a second coupling portion (15; 16; 27) delimited by a second side wall (14; 28); each first side wall (8; 30) being provided with at least one elastically deformable tongue (9; 31), which is laterally delimited by at least one slit (10, 11; 32), and has a hooking tooth (12; 33) designed to engage the second side wall (14; 28) following the coupling of the first coupling portion (7; 29) to the second coupling portion (15; 16; 27).
