Abstract
A connector for medical infusion/transfusion lines, catheters and the like, comprising a tubular body with a protection valve including an obturator formed by a resilient disk having a circumferential sealing edge normally co-operating under closing contact with an annular valve seat having a conical surface. On the side opposite to the annular valve seat, the obturator disk bears against an annular reaction surface of the body, and opening of the protection valve is operated by axial displacement of a tubular push member acting so as to press the central area of the obturator disk into the annular reaction surface thus elastically stretching it in the axial direction, whereby the circumferential sealing edge of the obturator disk radially retracts, moving away from the annular valve seat.
