ABSTRACT:
A sleeve grip for a pipe is radially expandable by axial compression from a bolt-nut system. One of the elements 8 of the bolt-nut system 13 is connected to a bidirectional drive motor 23 inducing rotation in the cylindrical pipe 2 and the other element 24 to the movable disc 25 of a brake 14. Thus, by simple tightening or slackening of the brake 14 and activation of the motor 23 inducing rotation in the pipe, it may be held by the expandable sleeve grip 12 or released.
