Round Bar Retaining Clip Identify

[brooker2008uk]

Hi all, i am wondering can anyone please help me in identifying the clip or component on the picture below. i know it is not the clearest but it basically is a component which slips on over the round bar and tightens some how which retains the bar from being pulled through the hole.

Please have a look and many thanks in advance.
