A disposable seal is provided for a luer lock end fitting, e.g. for a biopsy channel of an endoscope. The fitting has a tubular luer lock device and a retaining ring surrounding the tubular device. The seal is unitarily molded of a soft elastomer and has a double seal arrangement formed of an apertured end wall and a one-way-opening slitted plate or web behind the end wall. A distal end of the seal fits over the tubular luer lock device. This distal end has a radial cuff that seals against a flat transverse surface of the retaining ring and a frustoconic tapered protruding member which fits against a similar inner surface of the retaining ring to ensure that the cuff sealably engages the retaining ring under overpressure conditions.
