A joint for panels for covering floors, the joint comprising: - a covering profile that has at least one extension with a hidden face (1.1) to be arranged facing the floor and an exposed face (1.2), opposite to the hidden face (1.1) and to be arranged so that it is visible; - a base profile with a resting face (2.1) to be arranged making contact with the floor and a supporting face (2.2) to be arranged facing the hidden face (1.1); - coupling elements to establish a coupled arrangement between the covering profile and the base profile, comprising: ∘ two coupling portions (2.A; 2.B) on the base profile, each of the two coupling portions (2.A; 2.B) being defined according to a different angle with respect to the resting face (2.1); ∘ an attachable element (1.A; 1.8) to be coupled with any one of the two coupling portions (2.A; 2.B), the attachable element (1.A; 1.B) being projected from the hidden face (1.1); such that the coupled arrangement can be established such that the exposed face (1.2) has a different inclination with respect to the resting face (2.1) according to each of the two coupling portions (2.A; 2.B); characterised in that one of the following alternatives applies: (i) the attachable element (1.A) is configured as a female element and the two coupling portions (2.A) are configured as male elements, so that the coupled arrangement is established by inserting any one of the two coupling portions (2.A) into the attachable element (1.A); and (ii) the attachable element (1.B) is configured as a male element and the two coupling portions (2.B) are configured as female elements, such that the coupled arrangement is established by inserting the attachable element (1.B) into any one of the two coupling portions (2.B). - a covering profile that has at least one extension with a hidden face (1.1) to be arranged facing the floor and an exposed face (1.2), opposite to the hidden face (1.1) and to be arranged so that it is visible; - a base profile with a resting face (2.1) to be arranged making contact with the floor and a supporting face (2.2) to be arranged facing the hidden face (1.1); - coupling elements to establish a coupled arrangement between the covering profile and the base profile, comprising: ∘ two coupling portions (2.A; 2.B) on the base profile, each of the two coupling portions (2.A; 2.B) being defined according to a different angle with respect to the resting face (2.1); ∘ an attachable element (1.A; 1.8) to be coupled with any one of the two coupling portions (2.A; 2.B), the attachable element (1.A; 1.B) being projected from the hidden face (1.1); ∘ two coupling portions (2.A; 2.B) on the base profile, each of the two coupling portions (2.A; 2.B) being defined according to a different angle with respect to the resting face (2.1); ∘ an attachable element (1.A; 1.8) to be coupled with any one of the two coupling portions (2.A; 2.B), the attachable element (1.A; 1.B) being projected from the hidden face (1.1); such that the coupled arrangement can be established such that the exposed face (1.2) has a different inclination with respect to the resting face (2.1) according to each of the two coupling portions (2.A; 2.B); characterised in that one of the following alternatives applies: (i) the attachable element (1.A) is configured as a female element and the two coupling portions (2.A) are configured as male elements, so that the coupled arrangement is established by inserting any one of the two coupling portions (2.A) into the attachable element (1.A); and (ii) the attachable element (1.B) is configured as a male element and the two coupling portions (2.B) are configured as female elements, such that the coupled arrangement is established by inserting the attachable element (1.B) into any one of the two coupling portions (2.B).
