Abstract

A fiber optic connector of the so-called D-4 type incorporating means for incrementally adjusting the fiber core supporting ferrule with respect to an alignment projection which engages a corresponding recess in an adapter when the connector is engaged with the adapter. In addition to the usual radially arranged slots in a key member which are selectively engaged by a corresponding projection on a ferrule supporting element during the adjustment procedure, the device includes a slidably mounted snap ring which is pushed into locked engagement to prevent loss of final adjustment. The snap ring is moved to this position by a selectively engageable adjustment tool which also serves as a protective cap.
