Remove space between authors in citation

Question

I was wondering if I can remove the space between the authors in citation.

I edited my citation style this way:

\usepackage{csquotes}
\usepackage[backend=biber,style=apa, maxcitenames=3,natbib=true,doi=false]{biblatex}
\LetLtxMacro{\cite}{\citet}                     %Jahr in Klammern
\renewcommand{\labelnamepunct}{\addcolon\space} %Doppelpunkt statt Punkt
\DeclareDelimFormat*{multinamedelim}{\,/\,} 
\DeclareDelimFormat*{finalnamedelim}{} 
\DeclareDelimAlias{finalnamedelim}{multinamedelim} 
\DeclareDelimFormat*{finalnamedelim:apa:family-given}{}
\DeclareDelimAlias{finalnamedelim:apa:family-given}{multinamedelim}

Now I'm almost done but I don't want the space between the slashes.

Anyone an idea? Thank you. :D

I'd guess you only need to replace \DeclareDelimFormat*{multinamedelim}{\,/\,} by \DeclareDelimFormat*{multinamedelim}{/}. — , Nov 02 '19 at 17:12
@Schrödinger'scat Do you want to type up a short answer here, so we can mark this question as answered? — moewe, Nov 04 '19 at 16:12
@moewe It might be better if you give a real answer from an expert. I was only guessing. — , Nov 04 '19 at 16:13
@Schrödinger'scat Ok then, I typed up something below. Your guess was spot on though, and I dare say slightly more than a wild guess. If you change your mind I can remove my answer. — moewe, Nov 04 '19 at 16:33

As Schrödinger's cat points out in the comments it is enough to get rid of the two \,s in the definition of multinamedelim, since they add the space around the slash.

It should be noted that this modification of biblatex-apa no longer conforms to APA style and that I usually recommend not using biblatex-apa if you don't want APA style, since the style can be harder to customise because it is designed to implement APA guidelines as closely as possible.

Instead of the now deprecated \labelnamepunct it is usually nicer to redefine the context-sensitive nametitldelim for the bib context.

Finally, it should be noted that the code could be shortened by explicitly giving the values for finalnamedelim and finalnamedelim:apa:family-given instead of clearing them first and then using aliases. But even though the version with aliases is longer (and arguably looks clunkier - I'll say that because I'm pretty sure I have used that idiom before), I prefer it because it requires no repetition of the actual value / of the delimiters.

\documentclass[ngerman]{article}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage{babel}
\usepackage{csquotes}
\usepackage[backend=biber, style=apa, maxcitenames=3, natbib=true, doi=false]{biblatex}

\DeclareDelimFormat[bib]{nametitledelim}{\addcolon\space}

\DeclareDelimFormat*{multinamedelim}{/} 
\DeclareDelimFormat*{finalnamedelim}{} 
\DeclareDelimAlias{finalnamedelim}{multinamedelim} 
\DeclareDelimFormat*{finalnamedelim:apa:family-given}{}
\DeclareDelimAlias{finalnamedelim:apa:family-given}{multinamedelim}

\addbibresource{biblatex-examples.bib}

\begin{document}
\cite{sigfridsson,companion}
\printbibliography
\end{document}
