We need to know which part you are talking about.
Is this the top telescoping bar with the back tightening knob?
Or the lower telescoping channel with the black handle lever where the lever handle fits into a series of holes in the side of the channel?
I 110% agree with Sunline Fan, do not take the gray end cap off the awning tube but we do not know what part you are referring to.
Here is the "lower" arm with the lever handle
Here is both the upper and the lower. The Star and spinner twirly thing is hanging off the "top" telescoping bar with the black knob you tighten up.
Hope this helps
