ABSTRACT:
A coupling wherein a spherical or ring-shaped female coupling member has sockets for pins at the ends of rod-shaped male coupling members. Each pin has a conical displacing portion in front of a cylindrical peripheral surface which is formed with a pair of recesses, and the female coupling member contains a pair of movable retaining elements for each socket and springs, rubber pads or like parts which bias the retaining elements into the recesses of a pin in the respective socket. The conical displacing portion serves to spread the retaining elements apart during introduction of the pin into a selected socket, and the pin is thereupon secured in inserted positoin by an internally threaded sleeve which surrounds the end of the rod and can be moved into abutment with the external surface of the female coupling member in order to urge undercut portion of surfaces in the recesses of the inserted pin against the respective retaining elements. The pin can be extracted from its socket upon retraction of the sleeve and rotation of the rod-shaped coupling member relative to the female coupling member so that the peripheral surface of the pin spreads the respective retaining elements apart and dislodges them from the recesses.
