The present invention relates to an insert for an optical fiber assembly through which an optical fiber element can be pulled out without damage. The insert is provided for guiding a part of the optical cable (2) which comprises at least one optical fiber element (3) and being accommodated in a housing of the optical fiber assembly, wherein said part of the optical cable (2) has a cut-out portion in which a jacket of said optical cable (2) is partially removed, thereby exposing said at least one optical fiber element (3). The insert (1) comprises an optical cable guidance means (4) for guiding said optical cable (2) across the insert (1); a recess (5) surrounding the exposed optical fiber element (3) and a bend element (6) arranged at an end portion of the recess (5) and projecting from the recess (5) in a curved manner.
