If understanding correctly, you're wanting an Add Connection (Friend) button? This really can't be done without a new integration because the CB Menu link is dynamic to the situation. For example if already connected it becomes a Remove Connection, if not logged in then is not visible at all, etc.. At any rate the below HTML is used by the add connection link which you could paste directly to a delimiter field (required as you need substitutions for this to work).
Code:
<a name="cbAddConn" onclick="return overlib('Personalize your invitation to connect by adding a message that will be included with your connection.<br /><form action="index.php?option=com_comprofiler&act=connections&task=addConnection&connectionid=[user_id]" method="post" id="connOverForm" name="connOverForm">Message:<br /><textarea cols="40" rows="8" name="message"></textarea><br /><input type="button" class="inputbox" onclick="cbConnSubmReq();" value="Submit" /> <input type="button" class="inputbox" onclick="cClick();" value="Cancel" /></form>', STICKY, CAPTION,'Connect to [username]', CENTER,CLOSECLICK,CLOSETEXT,'CLOSE',WIDTH,350, ANCHOR,'cbAddConn',CENTERPOPUP,'LR','UR');" href="javascript:void(0)">Request Connection</a>
