Abstract: A coupling for furniture components includes two cheeks, each including a plurality of seats which, when matched, define housings for tubular elements such as furniture legs to be secured between the two cheeks. Each seat opens at the edge of the respective cheek and has a cross-section defining, with a facing seat, a housing with a cross-section that is slightly less than that of the tubular element to be secured. In one embodiment, a flat longitudinal wall in the seat blocks the rotation of the tubular element within the housing. Each seat in at least one cheek is also provided with a projecting element cooperating with a complementary aperture defined in the tubular element, and in one embodiment has an arched portion extending from the seat towards the facing cheek to define a closed cross-section that engages the tubular element.
