Your harnesses aren't "finished up" around the harness bar. The end of the harness strap needs to wrap back over and into the clip. This "locks" the strap and ensures they cannot come loose.
From my rally car:
If you were to leave your harnesses as you currently have them, in an accident the strap can slide out of the clip and you'll lose the shoulder belts (not good!). You need to follow the instructions on page 24 and 25:
http://www.schrothracing.com/sdocs/2...structions.pdf I wouldn't worry about the wrap instruction on page 27, it's difficult to do and the style on pg 25/25 is perfectly fine if you have the clips close to the bar like you do.
Looking at your harness I think you may need to go back to Schroth and/or the shop you bought them to get harnesses that have longer shoulder straps. It's a pretty common request, so I don't think you'll find them difficult to get.
Can you take some photos of your lapbelt mounting? Might as well tell you if they're safe at the same time
