When it comes to Genuine Honda clutch parts, broken springs or ones that have worn through their retaining lips are a result of poor clutch technique.
Poor clutch technique involves bumpy, jerky, or harsh engagement. Each bump or jerk compresses the springs more than a smooth engagement would. Each excessive compression weakens the springs a little, and wears away the retaining lips a little. Eventually, a spring will either break or escape from its little jail.
Aftermarket clutches may not be as well-made as OE, so broken or escaped springs may be due to poor materials or construction, instead.
An OE clutch, properly used, will last over 250,000 miles. I know, I've done it. My original clutch was replaced at 255,800 miles. I now have 131,200 on the replacement.
