I believe the answer is:

<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">in-crowd</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for clique that I've seen before include "Group of friends" , "Close-knit group of people who don't encourage outsiders" , "Exclusive group of people" , "'Exclusive circle of people, hostile to outsiders (6)'" , "Close-knit exclusive group" .)
