A fiber optic connector comprises a housing member and ferrule members. The housing member is rigid and has a profiled bore extending therethrough. The bore has a central cylindrical bore portion, tapered bore portions on each side of the central cylindrical bore portion, and a support bore portion at the outer end of each tapered bore portion. The ferrule members are of resilient deformable material and are teminated onto fiber optic transmission members. Each ferrule member has a profiled front end comprising a front cylindrical section of slightly larger diameter than the central cylindrical bore portion, a tapered section slightly smaller than the corresponding tapered bore portion and an alignment section for tight engagement with the corresponding support bore portion. A coupling member engages shoulder members of the ferrule members urging the profiled front ends into the profiled bore with the front cylindrical sections tightly engaging the central cylindrical bore portion thereby applying a radial compressive force to the front cylindrical sections and centering the fiber optic transmission members and the alignment sections of the ferrule members tightly engaging the corresponding support bore portions of the housing member to maintain the ferrule members and their fiber optic transmission members therewithin in axial alignment when lateral forces are applied to the ferrule members.
