This is supposed to be a closed custom shape WITHOUT the straight line!

How can I get rid of this unwanted line?

Putting '-- cycle' at the end makes no difference.

I saw Phelype's comment and deleted the post. Now I am undeleting it per request. But I will be happy to delete it again. In any case, full credits go to Phelype Oleinik, who was the first to propose a solution.

In fact, I like Phelype's proposal better than "just removing the line". Here is why:

Reversing the arc:

begin{tikzpicture}

draw[fill=blue] (-4.261,2.617)..controls (2.5,1.5) and (-4.5,-3)..(3.908,-3.118) 

 arc (321.42:148.44:5);

end{tikzpicture}



Just removing the line:

begin{tikzpicture}

draw[fill=red] (-4.261,2.617)..controls (2.5,1.5) and (-4.5,-3)..(3.908,-3.118)

      (-4.261,2.617) arc (148.44:321.42:5);

end{tikzpicture}

end{document}

The blue corresponds to what I would suggest, namely reversing the arc, and the red one "removing the line", which works at the level of the contour but does not yield a continuous path.

And here is a second reason why I like Phelype's method better.

begin{tikzpicture}

draw [line width=1mm,line join=round]

(-4.261,2.617)..controls (2.5,1.5) and (-4.5,-3)..(3.908,-3.118) 

 arc (321.42:148.44:5) -- cycle;

end{tikzpicture}

begin{tikzpicture}

draw [line width=1mm,line join=round]

 (-4.261,2.617)..controls (2.5,1.5) and (-4.5,-3)..(3.908,-3.118)

      (-4.261,2.617) arc (148.44:321.42:5);

 draw[red] (-4.261,2.617) circle[radius=3mm]

 (3.908,-3.118) circle[radius=3mm];   

end{tikzpicture}

I didn't know that the path has to be filled. So I update my answer as follows:

1. remove -- from the path and


2. pass the option even odd rule if the filling is needed.

Answer updated to add a hole in the fill
