Abstract
A luer-type connector comprising a male-component formed with a locking nozzle having a coaxially extending nozzle lumen, and a locking collar rotatable over said nozzle. The locking collar has a rear end and is formed with an internal thread for screw coupling with a corresponding thread of a radially extending annular lug of a mating female-component of the connector. The nozzle is formed with a ridge having a radially extending abutting wall surface facing the rear end of the locking collar and a peripheral surface extending forward from the abutting wall. An annular rim behind the abutting wall has a first diameter. An annular notch intermediate the abutting wall and the annular rim has a second diameter lesser than that of the first diameter. The locking collar is formed with a radially extending wall surface engageable with the abutting wall surface of the ridge. And an annular bulge behind the radial wall surface has a third diameter lesser than the first diameter. The annular bulge has an axial length lesser than an axial length of the annular notch and at least one locking surface of the locking collar having a diameter for interference fit with the corresponding peripheral surface and the annular rim of the nozzle.
