Title: Luer-type connector

Abstract: A luer-type connector comprising a male-component formed with a lockingnozzle having a coaxially extending nozzle lumen, and a locking collarrotatable over said nozzle. The locking collar has a rear end and isformed with an internal thread for screw coupling with a correspondingthread of a radially extending annular lug of a mating female-component ofthe connector. The nozzle is formed with a ridge having a radiallyextending abutting wall surface facing the rear end of the locking collarand a peripheral surface extending forward from the abutting wall. Anannular rim behind the abutting wall has a first diameter. An annularnotch intermediate the abutting wall and the annular rim has a seconddiameter lesser than that of the first diameter. The locking collar isformed with a radially extending wall surface engageable with the abuttingwall surface of the ridge. And an annular bulge behind the radial wallsurface has a third diameter lesser than the first diameter. The annularbulge has an axial length lesser than an axial length of the annular notchand at least one locking surface of the locking collar having a diameterfor interference fit with the corresponding peripheral surface and theannular rim of the nozzle.
