Telescopic assembly with locking device in retracted configuration

A telescopic assembly comprising:

• a first tubular body extending along a main axis;
• and a second tubular body comprising an enlarged portion and a rod, said rod being capable of sliding into a first axial end of the first tubular body for movement between an extended configuration and a retracted configuration;
• the telescopic assembly further comprises a device for locking the retracted configuration, said locking device comprising a ferrule extending along the main axis, a first axial end of said ferrule being positioned around a first end of the rod of the second tubular body, close to the enlarged portion;
• a second axial end of the ferrule comprising an internal stop;
• the first axial end of the first tubular body comprising a counter-stop, capable of cooperating with said internal stop to lock the first tubular body and the ferrule in translation;
• the ferrule being locked in axial translation relative to the second tubular body and rotatable around said second body, between an unlocked position and a locked position,
• the telescopic assembly being such that:
• in the unlocked position, the internal stop is angularly offset relative to the counter-stop, so as to allow the sliding of the second tubular body into the first tubular body between the extended configuration and the retracted configuration;
• and
• in the locked position, the internal stop is angularly aligned with the counter-stop, so as to lock the second tubular body in the first tubular body in the retracted configuration.
