Bandit awning

Hi, i recently acquired a new unused bandit awning with three lengths of figure of 8 plastic section. I take it one side slots onto the guttering but how does the awning tunnel fix to the figure of 8 section?. Ta for any info.

 

The awning tunnel should have a piped section on the end which slides into one side of the figure 8

 

Ok thanks , i'll get it out and have a look, it's never been out of the bag yet !
