A maneuvering member for selectively attaching an actuating rotary member to a head portion of a drilling assembly. The maneuvering member includes a frame having an axial-symmetrical tubular portion internally delimited by a cylindrical mantle. The frame includes a first end that selectively interfaces with the actuating rotary member, and a second end provided with an alignment member for interfacing with a corresponding alignment member of the head portion of the drilling assembly. Hydraulically actuated blocking means is positioned at the second end and includes a pin that is actuated by a hydraulic fluid in a radially movable manner with respect to the frame at the second end. The pin is actuated between a back position in which the pin is arranged flush with the cylindrical mantle, and a forward position in which the pin projects inside the cylindrical mantel to selectively release/secure the head portion of the drilling assembly.
