Consider the following MWE
documentclass{article}
usepackage{tikz}
usetikzlibrary{decorations.pathmorphing}
begin{document}
begin{center}
begin{tikzpicture}
draw[thick] (3,-0.5)--(3,-0.8)--(0.2,-0.8)--(0.2,0.8)--(3,0.8)--(3,0.5);
draw[thick,decoration={zigzag,segment length=2mm}] decorate{(3,-0.5)--(3,0.5)};
end{tikzpicture}
end{center}
end{document}
This is the output shown by this code:
Note that the point where the zigzag and the straight lines combine doesn’t have nice finishing, as shown in this figure.
How to achieve the correct finishing??
Splitting a draw
command into two is not a good idea. Try like this:
begin{tikzpicture}
draw[thick] (3,-0.8)--(0.2,-0.8)--(0.2,0.8)--(3,0.8)--(3,0.5) decorate [decoration={zigzag,segment length=2mm}] { -- (3,-0.5)} -- cycle;
end{tikzpicture}

Your figure is composed of two paths and is therefore not closed, which is why there is this discontinuity.
The idea is to make a single closed path and using the options pre=lineto,pre length=5pt,post=lineto,post length=5pt
just give the coordinates of the four vertices of the rectangle.
documentclass[tikz,border=5mm]{standalone}
usetikzlibrary{decorations.pathmorphing}
begin{document}
begin{tikzpicture}
draw[thick](3,-0.8)--(0.2,-0.8)--(0.2,0.8)--(3,0.8)
decorate[decoration={zigzag,segment length=2mm,pre=lineto,pre length=5pt,post=lineto,post length=5pt}] {--cycle};
end{tikzpicture}
end{document}
