Delete dots and number of a page in the table of contents [closed]

Question

In order to hide the Bibliography word I am using

\documentclass[a4paper,12pt{book}
\begin{document}
\tableofcontents
\addcontentsline{toc}{chapter}{Bibliographie}
\renewcommand\bibname{Bibliographie}
\chapter*{Bibliographie}
\renewcommand{\bibname}{}
\begin{thebibliography}{99}
\end{thebibliography}

The problem is that is the table of contents I have dots and the number of the corresponding page in the table of contents.

How can I delete those dots and the number of the corresponding page in the table of contents?

Thanks

Answer 1

There are no dots in your example, but to remove the page number:

\documentclass[a4paper,12pt]{book}
\begin{document}
\tableofcontents
\renewcommand\bibname{Bibliographie}
\chapter*{Bibliographie}
\addtocontents{toc}{{\bfseries Bibliographie}}
\renewcommand{\bibname}{}
\begin{thebibliography}{99}
\end{thebibliography}
\end{document}
