Abstract: A two-piece optical fiber connector comprises an internal member and an external member. The internal member includes a block having a hole which receives the end of an optical fiber cord and cantilevers provided along the side walls of the block having internal and external projections when no force is applied. The external member includes an opening through which the optical fiber cord is inserted and an opening or recess which engages with the external projections of the cantilevers when the block of the internal member is fit into the external member axially and slidably. Once the internal member and external member are fitted, the internal projections on the cantilevers securely hold the optical fiber cord in place.
