Abstract
Connector, particularly for use in underwater well installations, for securing members together under large clamping forces. The connector is characterized by two successive stages of actuation of a locking means, typically a split ring or set of arcuate segments, with the actuating force of the second stage being applied by camming surfaces via low friction means to establish a high compressive preload without use of especially large power devices.
