Pnuematic Question?

Hi, in our robotics class we were challeneged to make a device to throw an orbit ball as far as we can using only pnuematics, PVC, wood, rope, twine, string and fasteners. We are designing a ballista, in which the pnuematic actuator will pull back a rope and then release it. However, I fear that in our last calss period, when we are building like the whole system (minus pneumatics), we will make a hook that pulls back the rope and then dosen't let it go. Does anyone know of a sure-fire way to design a hook that will stay on during the pull back and release when it stops?

Thank You.
