-25- Abstract of the Disclosure The invention pertains to a connector for connection to a wellhead in generally coaxial alignment therewith. The con- nector includes a generally tubular main body and latches carried by the main body for radial extension and retraction with respect thereto to engage the wellhead and latch the connector to it. A set of circumferentially spaced support members are also carried by the main body longitudinally adjacent the latches for radial extension and retraction at least partially independently of the latches. The support members and main body have abutting slide surfaces extending parallel to the path of movement of the support members, while the support dogs and the latches have abutting support surfaces inclined with respect to said path of movement for wedging the latches longitudinally as the support members are extended. An actuator on the main body is operatively associated with the latches and support members to extend them successively toward the wellhead.
