Try this it will work :

Html :

<span class="topmid-left">Connected to <b>My Site 'test.com'</b> </span>

Script :

// return the inner text of <b>.
var boldText = $("span.topmid-left b").text(); 

// returns the array of length 3.
var splitArr = boldText.split('\''); 

// returns test.com
var text = splitArr[1];

// replace the text.com with abc(or any text you want).
var repText = boldText.replace(text, "xyz"); 

// [Output] My Site 'xyz'
console.log(repText);

// assign new text into html <b> tag.
$("span.topmid-left b").text(repText);
