You don't describe how and what part snapped ? How long you have had it ? 
Things get worn out. You should inspect your gear BEFORE heading out. Definately before loaning it out. 
If the cord snapped, re-tie it. If the stitching came undone, take it to a boot shop and have them re-sew it. If the kite is new, contact HQ by
internet and they'll probably send a replacement strap. 
Play safe and stay in school. Get your M8 to teach you the Queens English !
