You mean the strap tore off?
If so doesn't cost much to unpick the first little bit of the luff tube and sew a new strap in - if you want adjustable you'll be paying extra for the buckle unless you find an old sail with an adjustable head, cut that off and take it to the sailmakers and then you're only paying 20min labour

Or did your mast poke thru the luff tube? Then again, about the same cost to patch it I guess
