An arrangement in a remote-controllable subsea connector wherein the connector components may be locked together by the aid of a ring of collet fingers (5) cooperating with an actuator ring (17) controllable in the axial direction of said connector. In order to provide secure and efficient locking of said connector without the necessity of exerting very high pressures, and in order to permit compensation of tolerance variations in the connector said actuator ring (17) is provided with a maneuver ring (8) and an annular shaped retaining means which may consist of a ring member, for instance of titium alloy or carbon fibres, or a series of retaining members (7) placed in an annular shape on the inside of said maneuver ring (8), in contact with said fingers (5) in said collet finger ring. Said retaining members (7) cooperate with said maneuver ring (8) via conical surfaces (19, 13). On their surfaces facing fingers (5) said members (7) have a cylindrical portion (12) which cooperates with a plane surface on fingers (5) and transmits the connection forces.
In an arrangement in a remote-controlled subsea connector, expecially for use in oil production systems, wherein the connector components may be locked together by the aid of a collet finger ring and an actuator ring that is controllable in the axial direction of said connector for fingers of said collet finger ring, the improvement wherein said actuator ring further comprises a maneuver ring, and a radially flexible annular shaped retaining means in contact with the maneuver ring, and positioned against the fingers of the collet finger ring,
