As Joel points out, the way to do this is to create a custom patch 
residue. See http://salilab.org/modeller/FAQ.html#9 and 
http://www.charmm.org for more details on CHARMM patch residues. The 
link you posted describes how to create a new residue type, not how to 
make a link between two existing residues.

The example in the FAQ is for a disulfide, but I imagine your linkage 
would be similar. As you already discovered, this patch residue should 
go in modlib/top_heav.lib.
