The reflector is mounted on a single spoke of a spoked wheel and comprises plate member having a body portion disposed between opposed end portions. A spoke is received in appropriate recesses in the body portion adjacent to the end portions with the body portion disposed on one side of the spoke and the end portions on the opposite side of the spoke. Tab means on the respective end portions of the member serve to generally preclude a dislodgement of the reflectors during operation of the spoked wheel.

An anti-friction bearing interposable at the crossing-over point between two spokes of a bicycle wheel comprises a body having a through hole, with a completely closed continuous part, and giving out onto two opposite ends of the body to receive through it one of the two spokes. The body further includes a portion of external surface in contact with the other spoke.

A spoke clip including a plate, spoke channel and at least two tie holes. The plate includes a front face, back face, sides, top and bottom. The sides of the plate define the thickness of the plate. The thickness being thin enough to allow the plate to fit between two spokes which cross each other. The spoke channel is part of the back face to receive a spoke of a wheel. The least two tie holes are through the front and back faces.

A reflex reflector (11) has a reflector body (12), and attaching means (13) which are provided on the right and left sides of the reflector body (12), and is adapted to be attached between spokes (5) of a spoked wheel. Each of the attaching means (13) includes a passage (14) for fitting a spoke (5) therein laterally of the wheel, and the passage (14) has lateral surfaces positioned laterally of the fitted spoke and back surfaces positioned at the back. The attaching means (13) further includes lateral projections (18, 19) projecting to the lateral surfaces of the passage (14) and adapted to make the width of the passage (14) smaller than the diameter of the spoke (5). The lateral projections (18, 19) have elasticity which allows the amount of projection from the lateral surfaces of the passage to be decreased, whereby the spoke (5) is allowed to move beyond the lateral projections (18, 19) to reach a predetermined position. The attaching means (13) further includes a back projection (20) projecting to the back projection of the passage (14), and the back surface (20) has elasticity which allows the amount of projection from the passage (14) to be decreased.

A connector for a fiber optic member comprises a ferrule in which is positioned an insert surrounding a section of the fiber optic member adjacent an exposed end of the fiber optic member, the exposed end extending along a front bore of the ferrule. A crimping ring on the ferrule is controllably crimped thereon thereby moving arcuate sections of the insert into mechanical engagement with the fiber optic member with no or minimum deformation to the fiber optic member and securing the fiber optic member in the ferrule. A single crimping ferrule can be used if desired.
