Both, in my opinion. But it was not tightened snug. There's only one screw that both adjusts the tension and disconnects the collar. You have to loosen the screw quite a bit to allow the camera to rotate easily. To remove the collar you have to pull the knob away from the lens against spring tension to release the collar. Even with the screw loosened up you would think the tripod collar would stay attached because there is a spring pushing the detent down in the "locked" position.
The knob was loose enough so the camera would rotate. I went to move about 20yds so I locked the ball head in position but forgot to tighten the tripod collar knob back down. I set the camera over my shoulder and as soon as I felt the weight of the camera on the back of my shoulder I felt the collar let go of the camera. It fell behind my back and the screen landed on a rock.
I've been stopping on the way home from work almost every morning and shooting some sillouette pelicans that land on a pole. Well I got tired of hand holding, waiting on them to make a pose so I brought the monopod yesterday to try the 100-500 on for the first time. I had no problems yesterday but I dud snug the screw back down before putting the camera on my shoulder.
This morning I forgot to tighten the screw back down on the collar. So it was my fault for not tightening the screw back down but I feel if it were designed properly it should not have let go even with the screw loosened up. (I mean you have to leave the screw fairly loose to be able to easily rotate the camera).
I just wanted to share this so everyone is aware and hopefully it won't happen to you.
Here's a few images of the pelicans. The last two were from yesterday and that was the first time I tried the monopod on this lens. The wind was wrong so they were facing away from me unfortunately...
