ABSTRACT:
An improved luer lock connector having a pair of tapered engagement surfaces between the hub and one of the two components of the luer connector. The tapered engagement surfaces provide a gradual frictional engagement when tightening the hub to minimize inadvertent reverse rotation and loosening of the hub. The tubular body is also provided with a plurality of axially extending splines for engagement with a plurality of inwardly radially directed ribs on the hub to positively rotationally lock the two components when the hub is in a proximal position. A small circumferential ridge provides tactile feedback to an operator to indicate when the hub is in a positive rotationally interlocked relationship with the tubular body. The hub may be completely removed in a proximal direction from the tubular body and retracted proximally along a supply line to remove it from the connector site.
