A luer connector (10) is provided with a tactile and audible torque indicator. The indicator comprises a detent incorporated between the female cylindrical component (14) of the luer connector and a rotatable collar (32) mounted thereon. As the collar (32) is turned in a clockwise direction, the collar is impeded by the detent formed by opposingly projecting protuberances (34, 38) between the inside of the collar and the outside of the female cylindrical luer component (14). As the threaded luer connection is tightened, requiring additional torque to tighten it further, the additional torque overcomes the resistance of the detent, allowing the collar protuberance to slip past the cylinder protuberance. The female luer component may also be provided with a color patch or pattern (40), to indicate by its rotation, when the detent has been overcome, that the luer connection has been appropriately tightened. |
