<p>A safety mechanism (200) which can be applied to a syringe (100) to make it safe is described, comprising a needle-holder contrasting element (8) suitable to be made integral to the head of the syringe body (1), and a sleeve (5) which can be mounted by sliding on the syringe body (1) to pass from a retracted utilization position to an extended safety position where the needle (2) of the syringe is covered. The sleeve comprises at least one elastic tab (57) inclined towards the inside to block the contrasting element (8) when the sleeve is in the extended safety position. The contrasting element (8) comprises at least one cam surface (86) interacting with the elastic tab (57) to bend it towards the outside, following a relative rotation of the contrasting element (8) with respect to the sleeve (5) so as to allow the insertion of the contrasting element (8) into the sleeve (5).</p> |
