A spectacle rod is provided, including a plate-shaped metal rod and a friction element located at an ear bend. In order to avoid inadvertent removal of the friction element from the metal rod, a protrusion and the recess are formed. The protrusion and recess include a first transverse protrusion at the outermost second end of the spectacle rod. This transverse protrusion, together with the spectacle rod, forms an outwardly open recess. This recess has a smaller cross-section at the opening than at a central part. Thereby, elastic compliant material from the friction element will be received in the recess. The elastic material will be compressed so that a clamping effect occurs, contributing to a retention which prevents accidental separation of the friction element and the metal rod.
A spectacle rod with a first end part intended for connection with a front piece, as well as a second end part intended to be bent to form an ear bend, the spectacle rod having a longitudinal direction and a transverse direction, and the spectacle rod being formed, at least above the second end part of the spectacle rod, by a plate-shaped rod having side faces as well as bottom and top faces, and wherein a friction element made from an elastic, compliant material is connected to the plate-shaped rod in a position at the ear bend for contact behind the ear of a user, and wherein the plate-shaped rod has a first transverse protrusion, which first transverse protrusion is directed in the transverse direction and obliquely in the longitudinal direction in order to form, together with the second end part of the metal rod, a longitudinally open recess, and wherein, in the first end part of the friction element, a first transverse hole is provided for receiving the first transverse protrusion of the plate-shaped rod, and wherein the plate-shaped rod is a metal rod, and wherein the friction element is conduit-shaped so that the conduit walls and bottom cover the side faces and the bottom face of the metal rod, and wherein the first transverse hole of the friction element is formed in the material quantity and directed in the transverse direction in order to receive the first transverse protrusion of the metal rod, and wherein elastic material at the first end part of the friction element is received in the open recess of the metal rod, so that the first transverse protrusion and the recess form first retaining means, and wherein between the walls and the bottom of the conduit and the side faces of the metal rod, further retaining means are provided which prevent the displacement of the friction element in the longitudinal direction and transverse direction of the metal rod, wherein the first transverse protrusion of the plate-shaped rod is provided at its outermost second end, wherein the longitudinally open recess is formed, together with the outermost second end part of the metal rod, which longitudinally open recess has at its opening a smaller cross-section than at a central part of the recess, wherein the friction element at a first end of the conduit is closed by a material quantity at the first end of the friction element, wherein the first transverse hole of the friction element is formed in also directed obliquely in the longitudinal direction, wherein elastic material at the first end part of the friction element is received in the open recess of the metal rod in an elastically compressed state.
