Abstract: A connector including two connector portions each including a ferrule and a latch, each latch including a distal end, and a proximal end, wherein the latch is pivotable about an intermediate connection portion; and a boot mounted to the connector portions, the boot movable longitudinally relative to the connector portions, wherein the boot causes the distal ends of the latch to pivot toward the ferrule of each connector portion as the boot is moved away from the connector portions. Front housings of the connector portions can each be rotated about the longitudinal axis of the ferrule without rotating the ferrule or the boot, to change the polarity of the two connector portions. The spacing between the two ferrules is adjustable. A holder holds the connector portions, the holder including side slots, the connector portions mounted to the holder by moving laterally to the side slots. The holder defines an area for receipt of a fiber optic cable when the ferrule is pushed in a direction toward the boot.
