Abstract
This connector comprises two tubular members connected to each other, one of which can pivot about a rotation axis which forms an acute angle with the axis of the two members. This axis of rotation and the axes of the two members converge to the same point. Remote control means are operative to vary at will the relative angular position of the tubular members and means are adapted to lock said two members against relative rotation in a selected angular position.
