<aol> me too </aol> But I took my code from Javier's titletoc package.

Anyway here are the intances for `Homology Theory', James Vick, GTM #145,
Springer.   The leaders could be
  \leaders\hbox{\kern\@tempdimc\hbox{leader@action}} or xleaders...?
as this would make the effect of leaders-sep easier to guess.

\DeclareCollectionInstance{homology}{contentsobject}{chapter}{JK}
        {number-format=\textsc{Chapter~ #1}\\,
        boxed-number=false,
        pre-v-action= \addvspace{10pt},
        leaders-sep= 1.5pt}

\DeclareCollectionInstance{homology}{contentsobject}{section}{JK}
{       object-indent=12pt,
        number-format=\relax,
        leaders-sep = 1.5pt}

And contentsobject template contains
   \if@boxed@number
     \IfNoValueT{#3}{\def\COnumber@format##1{\hfil}}
     \hbox to \@tempdima {\COnumber@format{#3}}
   \else
     \IfNoValueT{#3}{\def\COnumber@format##1{\relax}}
     {\COnumber@format{#3}}
   \fi
