a molded top attached to said containment body said molded top including a substantially rectangular opening located between a first end portion and an opposing second end portion; and
a compression element positioned in said substantially rectangular opening for movement between a first position and a second position to apply force to each of said first crimp element and said second crimp element, said compression element occupying said first position for width adjustment of each said bore, of said first crimp element and said second crimp element, to receive the stripped, cleaved and polished end portion of the at least one optical fiber, said compression element occupying said second position for splicing said first fiber stub with the stripped, cleaved and polished end portion of the at least one optical fiber in said first crimp element and splicing said second fiber stub with the stripped, cleaved and polished end portion of the at least one optical fiber in said second crimp element;
a biasing element having a first resilient finger parallel with a second resilient finger, said resilient fingers restricting movement of said first fiber stub and said second fiber stub after mating of said connector plug with said optical fiber receptacle;
a bend relief boot having an opening therethrough to enclose said first end of said containment body and said first end portion of said molded top; and
a shroud for releasable engagement over said second end of said containment body and said opposing second end portion of said molded top.

Abstract
An optical fiber connector plug comprises a connecting portion including a rear entry at a first end and a first fiber stub exit opening to a first fiber stub channel. The first fiber stub exit is parallel to a second fiber stub exit opening to a second fiber stub channel. The first and second fiber stub exits are formed opposite the first end of the connecting portion. An optical fiber connector plug also includes a holder that fits into the rear entry of the connecting portion for permanent retention of at least one stripped, cleaved and polished optical fiber. First and second crimp elements, in the connecting portion, each have an open-ended bore coaxial with the fiber stub channels. Each crimp element contains an optical fiber stub. A molded top attached to the connecting portion includes an opening containing a compression element that forms splices by capturing a stripped, cleaved and polished end portion of an optical fiber and an optical fiber stub in each crimp element. A bend relief boot encloses the connecting portion at one end, while a shroud releasably engages it at the other end.
