Spectacles with interchangeable lateral arms, the spectacles comprising: - a front frame with opposed lugs for the hinged pivoting of the respective interchangeable lateral arms, and - a device for the removable coupling of each interchangeable lateral arm to the front frame, the device comprising a first and a second coupling element (8, 9), engaged in each other so as to be slidable from and towards a position of mutual retention, the coupling elements being configured for quick disengagement from this position, - the first coupling element being configured for the hinged connection to the corresponding lug of the front frame, and the second coupling element comprising a seat which is provided in the corresponding interchangeable lateral arm and which can be slidingly engaged by the first coupling element, - resiliently flexible retaining means being provided between the coupling elements (8, 9) of each interchangeable lateral arm to fix these coupling elements to each other in a removable manner, by means of a snap-fitting coupling, the first coupling element comprising a strip-shaped body with a first and a second branch (13, 14) of the strip-shaped body extending from a common portion into a direction of a predominant longitudinal extent and having their predominant longitudinal extents in directions parallel to each other, a theoretical strip plane being defined in the strip-shaped body, said strip plane extending parallel to the opposite surfaces of the strip-shaped body, which delimit the thickness of the strip-shaped body, when considered in a non-deformed flat configuration, characterized in that the branches (13, 14) are spaced apart and have a lateral extent in a first direction substantially perpendicular to the strip plane and are spaced apart and have a transverse extent in a second direction substantially parallel to the strip plane and perpendicular to the direction in which the branches predominantly extend, in such a manner that the branches (13, 14) of the strip-shaped body can engage the seat in the interchangeable lateral arm by bearing against opposing inner surfaces (12a, b; 12c, d) of the seat in both the first direction and the second direction, as a result of a resilient stress created in the branches (13, 14) of the strip-shaped body in these directions (X, Y). - a front frame with opposed lugs for the hinged pivoting of the respective interchangeable lateral arms, and - a device for the removable coupling of each interchangeable lateral arm to the front frame, the device comprising a first and a second coupling element (8, 9), engaged in each other so as to be slidable from and towards a position of mutual retention, the coupling elements being configured for quick disengagement from this position, - the first coupling element being configured for the hinged connection to the corresponding lug of the front frame, and the second coupling element comprising a seat which is provided in the corresponding interchangeable lateral arm and which can be slidingly engaged by the first coupling element, - resiliently flexible retaining means being provided between the coupling elements (8, 9) of each interchangeable lateral arm to fix these coupling elements to each other in a removable manner, by means of a snap-fitting coupling,
