A device for spectacles, such as a lug for the articulation of a spectacle arm or a central nasal support bridge, to a lens, the lens has a pair of holes for the locking of the mount member, has a pair of bush members rigidly connected to each other and has respective axial holes, there being provided in the mount member a pair of pin-type appendages capable of being inserted into the respective holes subject to the introduction of these latter into the corresponding lens holes, such that each bush member is interposed between an inner surface of the lens hole and a corresponding outer surface of appendage. Each pin-type appendage has localized protuberances that deform the corresponding coupling surface. The fixing device has at least one relief protruding from the outer wall of each appendage and extending on a helical course in the axial direction of the appendage.
