Abstract
The invention relates to a device comprising a syringe body (10) having an axial direction (A) and a bearing sleeve (18) inside which the body is arranged. The sleeve has at least one holding lug (22) co-operating with the syringe body, at a proximal end (10A) of the latter, in order to hold the body in relation to the sleeve. Said proximal end is fixed to a wedging surface (42) having radial crenulations forming dips (42B) and bumps (42A) and the holding lug is inserted into a dip in order to prevent a relative rotation of the syringe body (10) and the sleeve perpendicularly to the axial direction.
