I always use super glue - loctite for latex
edit: This one. A little pricey, but well worth it. Works for the non-latex aswell. You can even repair ripped silicone molds.
What Paul said
I'm wondering... why did they use a brad (pitt) instead of a split rivet, like one the abs section? Did they riun out of rivets?
Furthermore, could brads haven been used on the abs section aswell? It is the same principle...
