ABSTRACT:
The device has a box-like body rotatably supporting a spool for winding one or more cables, a pivot rigidly connected to the spool, and a knob engaging the pivot in screw thread engagement relationship for actuating the spool. The pivot is connected to a toothed ring which interacts with a ratchet mechanism for preventing cable from being unwound from the spool upon a rotational movement being imparted thereto by turning the knob in one direction, and which permits cable to be unwound from the spool upon turning the knob in another direction. A pawl element has one portion which slides within a helical seat defined by a flange rigidly associated with the spool, and another portion which slides within a guide formed radially on the box-like body, for limiting the stroke of the rotational movement of the spool.
