First you insert a captive square threaded nut INSIDE the tube of your tongue (held there by a spring), then when you put the tongue in the locking pin is inserted from the right, and screwed into the nut that is already there. This prevents the rattling. There is a locking socket that is placed over the end at the left, and locked with the key provided. Comes with it's own spanner too.
I'll post a picture when someone reminds me how to attach a file
