ABSTRACT:
In a device for coupling a cardan half-joint with a fixed structure, such as a device for the subsea anchoring of a structure which uses cardan joints, the improvement consisting in that the half joint is of the cross-beam type and the main forks are formed by two half shells and there is an undercut abutment having the shape of a poppet. A better distribution of the pull stresses on the members of the joint is thus obtained, means being also provided to prevent the rotation of the joint.
