LaTeX: Prevent line break in a span of text

How can I prevent LaTeX from inserting linebreaks in my \texttt{...} or \url{...} text regions? There's no spaces inside I can replace with ~, it's just breaking on symbols.

Update: I don't want to cause line overflows, I'd just rather LaTeX insert linebreaks before these regions rather than inside them.

\mbox is the simplest answer. Regarding the update:

TeX prefers overlong lines to adding too much space between words on a line; I think the idea is that you will notice the lines that extend into the margin (and the black boxes it inserts after such lines), and will have a chance to revise the contents, whereas if there was too much space, you might not notice it.

Use \sloppy or \begin{sloppypar}...\end{sloppypar} to adjust this behavior, at least a little. Another possibility is \raggedright (or \begin{raggedright}...\end{raggedright}).

Surround it with an \mbox{}

Also, if you have two subsequent words in regular text and you want to avoid a line break between them, you can use the ~ character.

For example:

As we can see in Fig.~\ref{BlaBla}, there is nothing interesting to see. A~better place..

This can ensure that you don't have a line starting with a figure number (without the Fig. part) or with an uppercase A.

Use \nolinebreak

Define myurl command:

\def\myurl{\hfil\penalty 100 \hfilneg \hbox}
