Yes, I have invented a plastic detachable rod tip that requires no glue to stay on. it threads on like a electrical wire nut connector with tappered threads inside for gip.
You can purchase them from me or look in sports houses this year,
My new design is for a quick fix called Grip Tip" it can be used as a temporary fix or permanent solution to the broken rod ends.
It faster and easier than the metal ones now, mine is new and unique compare and let me know,

Roland
