I have the same problem- a broken shockcord on my tent pole (REI Half-Dome 2, just 3 years old) plus a cracked plastic connection that happened when I was camping and trying to stabilize the poles to hold the tent for the overnight trip. I realize I can fix the shockcord - but what about the fitting? 

If/when I buy a new tent, I will research companies that offer repair or replacement of tent poles. Circularity is to be considered when a tent is designed and produced - consider the end of life, and how to bring it back to use. A company's responsibility - and now mine, since I own the tent.
