ABSTRACT:
A luer-type connector comprising a male-component formed with a locking nozzle having a co-axially extending lumen, and a locking collar rotatable over the nozzle and having a rear end, and formed with an internal thread for screw coupling with a radially extending annular lug of a mating female-component of the luer-type connector. The nozzle is formed with ridge having a rear, radially extending abutting wall surface terminating at an acute edge. The locking collar is formed with a ridge-engaging portion consisting of a first wall surface rearwardly tapering, and a second wall surface radially extending and adapted for engagement with the abutting wall surface of the ridge, whereby the first wall surface is adapted for frictional displacement along the acute edge and the second wall surface prevents further forward axial displacement of the locking collar with respect to the nozzle.
