Connectors for physically and optically connecting optic fibers of the expanded beam type. Each half of the connector includes a lens having a forward surface including a convex portion surrounded by an annular plano portion. Each lens has secured to it a ring member having a circumferential surface coaxial with the lens axis. The lens and ring member are disposed within a tubular member which locates the lens laterally of the axis but gives it small freedom to tilt. The two tubular members are connected by an intermediary member. Biasing means bias the lenses towards one another and hard spheres between the annular plano portions keep their planes parallel.
