Name delimiters in biblatex

Question

I want to replace all name delimiters by "--", so it shall be "Author1 -- Author2 -- Author3" instead of "Author1, Author2 and Author3".

Currently I am using this code:

\usepackage[citestyle=authoryear-comp,bibstyle=authortitle,sorting=nyt,dashed=false,%
maxcitenames=2]{biblatex}


\newcounter{mymaxcitenames}
\AtBeginDocument{%
  \setcounter{mymaxcitenames}{\value{maxnames}}%
}

\renewbibmacro*{begentry}{%
  \printtext[brackets]{%
    \begingroup
    \defcounter{maxnames}{\value{mymaxcitenames}}%
    \printnames{labelname}%
    \setunit{\nameyeardelim}%
    \usebibmacro{cite:labelyear+extrayear}%
    \endgroup
    }%
  \quad% or \addspace
}

I hope someone can help me - I am trying to get a bibliography which fits the rules of Deutsches Archäologisches Institut (DAI).

To change the delimiters to, e.g., dashes both for citations and in the bibliography, add the following to your preamble:

\renewcommand*{\multinamedelim}{~--\space}
\renewcommand*{\finalnamedelim}{~--\space}

Preamble code for changing the delimiters only in the bibliography:

\AtBeginBibliography{%
  \renewcommand*{\multinamedelim}{~--\space}%
  \renewcommand*{\finalnamedelim}{~--\space}%
}

Preamble code for changing the delimiters only for citations:

\let\oldmultinamedelim\multinamedelim
\let\oldfinalnamedelim\finalnamedelim
\renewcommand*{\multinamedelim}{~--\space}
\renewcommand*{\finalnamedelim}{~--\space}
\AtBeginBibliography{%
  \renewcommand*{\multinamedelim}{\oldmultinamedelim}%
  \renewcommand*{\finalnamedelim}{\oldfinalnamedelim}%
}
