    摘要: Improvement relating to rings for securing cords and chains to spectacle side pieces. The invention concerns a specific securing ring having a semi-circular cross section with a flat base that (Figure 1, A and B) is completely in contact with the side piece, doubling, in relation to a ring with a round cross section, the side piece contact area and hence the adhesion area. The adhesion and clamping features of the ring are further enhanced when both sections of the ring are passed through a cylindrical ring and join up to form a circle that fills the whole space and forms, under the compressive action, a bead on the circumference of each ringend, whereby the beads hold the ring locked in a clamping position. Application particularly in the spectacle making industry.
