Abstract: A strain relief apparatus which is especially useful with a standard fiber optic connector (10) having a cylinder backshell (12) with a pair of rearwardly-projecting arms (20, 22) that hold circular clamp elements (24, 26) to clamp to a circular optical fiber cable, which facilitates clamping to a fiber optic flat ribbon cable, or flat cable (40). A flat cable adaptor (54) has a groove (82) with front, rear, and middle groove portions (84, 86, 90) each of rectangular cross-section for receiving the flat cable. A jacket (94) of compressible material of about one inch length is wrapped around the flat cable and lies in the groove middle portion. Only the jacketed part of the flat cable is firmly pressed against the bottom wall (114) of the groove to clamp the flat cable to the adaptor. In one adaptor device, two identical adaptors (52, 54) are used, which form a circular recess (62) that receives the clamp elements.
