Abstract
A quick relief mechanism including a sleeve having an external circumferential groove and a locking ring located on the sleeve and sized to seat in the groove. The locking ring is split at one location to provide split-end portions, and a rotatable clamping device is provided with a recess for receiving the split-end portions. The recess has narrow and wide dimensions that serve to engage and disengage the split-end portions of the locking ring to effect closing of the locking ring in the circumferential groove when the clamping device is rotated to present a narrow dimension to the split-end portions, and to open the locking ring when the wide dimension of the elongated slot is presented to the split-end portions.
