The protector consists of a tubular body (1) with internal cylindrical hollow shape, open at both its ends, in which body (1) there is an internal ring-type protrusion (2) of minimum thickness and width, guaranteeing the retention of the needle carrier (3). Between the protrusion (4) of the needle carrier (3) and the narrowed front end (6) of the tubular body (1) there is a spring (7). The body (1) has elongated side slots (8) guaranteeing its catching and the catching of the syringe when it is used.
