Ant take out your jib and post a photo here to be sure.

But you may have a screw at each end of the jib.

If that is the case and your jibs are loose then to tighten you backoff the screw at the small end of the jib and tighten the screw at the large end of the jib. To be working correctly both screws will be tight locking the jib in the correct position.
