ABSTRACT:
Disclosed is pressure responsive holding apparatus for maintaining a first cylindrical element fixed against fluid pressure induced longitudinal movement relative to a second element generally circumscribing the first element. The apparatus includes a gripping device, carried by the first element, and reponsive to fluid pressure between the two elements by moving into anchoring engagement with the second element to hold the first element fixed relative to the second element with force which increases as the fluid pressure increases. In the embodiment shown, the holding apparatus is used to retain a bypass passage through a well packer set in a well conduit closed by preventing fluid pressure from raising a mandrel assembly within the packer body to open the bypass passage.
