Connectors, particularly remotely operated connectors used to connect underwater well members under large clamping forces, are provided with rigid rolling antifriction elements engaged between a camming surface and a cam follower surface for converting axially directed operating motion into radial movement of a contractible and expansible annular locking means.

In a connector for securing two members together under a large clamping force, the combination of a connector body adapted to be secured rigidly to one of the members; generally annular locking means having a frustoconical locking shoulder, and an annular cam follower surface concentric with the axis of the connector body and tapering axially with respect to the connector body, the locking means being supported on the connector body for radial movement between an inactive position, in which the diameter of the locking means allows the connector body to be moved axially relative to the other member to be secured so as to place the locking means in operative position relative to the other member, and an active position, in which the diameter of the locking means is such that said locking shoulder will engage coacting locking means on the other member to be secured; a driving ring having a generally annular axially tapering camming surface parallel to said cam follower surface and concentric therewith, said camming surface and cam follower surface being spaced apart radially; a plurality of rigid rolling antifriction elements disposed and retained between said camming surface and cam follower surface and engaged therewith; and means carried by the connector body and supporting the driving ring for axial movement between a first position, in which the camming ring allows the locking means to occupy said inactive position, and a second position, in which the locking means is forced by coaction of said camming surface, said rolling antifriction elements and said cam follower surface to occupy said active position.
