The requested symbol and several other similar ones are part of the package https://ctan.org/pkg/pgfornament. Below is a screenshot from the pages 20 and 21 of the manual. You see that your ornament is symbol number 88
. The manual also gives some information on the origin on those drawings.

Here is an actual example to achieve something similar to your example. My understanding is that the symbol is used on points specified by the typesetter and not after every paragraph. The command \ornamentSep
allows just this.
\documentclass{article}
\usepackage{pgfornament,multicol}
%The command itself does not require the package multicol, but the example below does. The command also respects the \twocolumn option
\newcommand{\ornamentSep}{\noindent\hfil{{\pgfornament[width=0.618033988749895\columnwidth,color=red]{88}}}}

A quick remark on the OP's comment of March 2019.
The command was designed for central alignment to the text which seems like a natural decision to me. For example, the option headsepline
of the widely used https://ctan.org/pkg/koma-script does the same. Furthermore, any element https://ctan.org/pkg/koma-script or https://ctan.org/pkg/memoir is aligned with respect to the body text, not the physical paper page, unless I am mistaken.
Many canons of page construction for the twoside
option set different widths of inner and outer margins. It should be possible to modify my command to adjust the ornament central to the page (if that is what the OP wants). I currently have no idea to do it elegantly and class independently. Such a solution should honor the binding correction, too. But I can offer you a dirty solution: You may manually shift like in the following modification where you need to adapt the space by yourself.
%uses the package changepage
\newcommand{\ornamentSep}{%
\ifoddpage%
\noindent{}{\hspace{-4.10cm}\pgfornament[width=0.5\pagewidth,color=red]{88}}%
\else%
\noindent{}{\hspace{-5.65cm}\pgfornament[width=0.5\pagewidth,color=blue]{88}}%
\fi%
}
I still believe that this is awkward but I do not want to insult you.
