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.

A medico-surgical connector assembly comprising a connector portion and a coupling member, said connector portion having a body with a Luer-tapered portion of plastic material and a locking ring having an aperture therethrough that embraces said body, said body and said aperture being shaped to prevent relative rotation of said locking ring on said body, said coupling member being formed with a plastic Luer-tapered portion shaped for fluid tight cooperating Luer engagement with the said Luer-tapered portion of said connector portion, said coupling member being formed with projections on its outer surface that are shaped to engage with means on the inner surface of said locking ring so that said coupling member can be retained in a fluid-tight seal with said connector portion by said ring, and said body being shaped to permit limited axial displacement of said ring along said body sufficient to enable fluid tight engagement of said cooperating Luer-tapered portions without engagement of the means on the inner surface of said ring with the projections on said coupling member.
