Luer lock type connection device for medical use having a nozzle in which an axial internal passage is formed. The nozzle includes a bearing connection surface and a proximal annular retention zone. The connection device also has a flange forming an axial open seat having a wall that includes a distal part with internal screw thread, and a transverse proximal part in which a central proximal retention opening is formed, and whose diameter is matched to that of the proximal annular zone of the nozzle. The proximal annular retention zone of the nozzle and/or the central proximal retention opening of the flange include a circular band or cord covered or treated with a roughening agent. |
