Abstract
Embodiments of the invention provide a clamp lock to secure a clamp around a pressure vessel, such as a split tank pool filter. The clamp lock includes a drive rack with at least one notch, and a housing with a rotatable drive gear, a locking pawl, and a receiving hole. The rotatable drive gear is capable of laterally moving the drive rack through the receiving hole, and the locking pawl is capable of engaging the at least one notch when the drive rack has been inserted a distance into the receiving hole. The distance correlates to a diameter of the clamp sufficient to secure the clamp around the pressure vessel.
