Abstract
A connector for medico-surgical tubing has a plastics body with a male Luer tapered forward portion that is shaped for engagement with a coupling member having a cooperating Luer tapered bore. The body has a rear portion of prismatic shape and square cross-section that is embraced by a square aperture in a rear flange of a locking ring. The locking ring has a cylindrical portion which extends axially of the connector and which has an internal screw thread for engaging cooperating projections on the coupling member. The locking ring is thereby free to slide axially along the prismatic portion of the connector body but is prevented from rotation relative to it. The rear of the Luer tapered portion projects above the surface of the prismatic portion to limit forward displacement of the locking ring.
