There is described a device for connecting a first mechanical waveguide and a second mechanical waveguide, comprising: a first body for receiving the first waveguide and a second body for receiving the second waveguide comprising: a tubular member comprising a first thread extending on an internal surface thereof a first tubular screw having a second thread on an external surface corresponding to the first thread and a third thread extending on an internal surface, a pitch of the second thread being greater than a pitch of the third thread and a second tubular screw having a fourth thread extending on an external surface corresponding to the third thread, the second tubular screw being threadingly and frictionally engaged with the first tubular screw a triggering member for rotating the first tubular screw and an indexer for limiting a rotation of the second tubular screw to at least an initial angular position.
