# Draw special arrow with latex

I searched to find a simple way of drawing something like the figure below using tikz, but I couldn't find. Can someone help me with this?

All one has to do is too search within this site...

\documentclass{standalone}
\usepackage{tikz}
\usetikzlibrary{decorations.markings,arrows.meta}
\begin{document}
\begin{tikzpicture}
\node[draw, minimum width=2cm, minimum height=1cm] at (0,0) (A) {A};
\node[draw, minimum width=2cm, minimum height=1cm] at (4,0) (C) {C};
\draw[double distance=15, thick,
postaction={decorate, decoration={markings, mark=at position 0 with {\arrow[xshift=5mm]{Straight Barb[reversed,length=2pt 0.7]}}}},
postaction={decorate, decoration={markings, mark=at position 1 with {\arrow[xshift=7mm]{Straight Barb[length=2pt 0.7]}}}}
] ([xshift=1em] A.east) -- node {B} ([xshift=-1em] C.west);
\end{tikzpicture}
\end{document}


Or

\documentclass[border=1cm]{standalone}
\usepackage{tikz}
\usetikzlibrary{shapes.arrows}
\begin{document}
\begin{tikzpicture}
