Abstract:
The present invention relates to a locking device (10), comprising a threaded rod (12) and a tapping tube (14), which are movable relative to each other. An outer surface of the tube includes a first anti-rotation form.
The device further comprises: a locking sleeve (16) positioned around the rod and comprising a second anti-rotation form (60, 62) capable of being assembled to the first anti-rotation form; and an elastic element (18) connected to the locking sleeve.
In a locked position, the first (38, 40) and second (60, 62) anti-rotation forms are assembled; and in a release position, said anti-rotation forms are axially spaced apart, whereby the tube is free to rotate relative to the sleeve.
