Claim:
1. A conductor pipe connector assembly for coupling a pressure containing component to a conductor pipe of a subterranean well, the connector assembly comprising: an annular slip bowl circumscribing the conductor pipe; an annular slip segment between the slip bowl and the conductor pipe, the slip segment having an upward facing sloped surface with a slips surface profile and a downward facing sloped surface that mates with a bowl lower sloped surface of the slip bowl; a slip actuation ring located radially between the slip bowl and the slip segment, the slip actuation ring having a downward facing sloped surface with an actuation surface profile in engagement with the slips surface profile of the slip segment, wherein the actuation surface profile has a saw tooth like sectional shape and mates with the slips surface profile, retaining the slip segment in engagement with the slip actuation ring when the piston member is moved towards an unengaged position; and an elongate annular piston member circumscribing the conductor pipe and coupled to the slip actuation ring, the piston member movable to an engaged position to urge the slip segment radially inward against the conductor pipe.
