ABSTRACT:
A double-barreled syringe is provided which includes a mixing tip which is detachable after the tip is locked to the syringe body, so that the tip may be replaced by a locking cap. Locking occurs when a neck extending from the body between two shoulders is inserted into a bore in the tip (or, alternatively, the cap) and the tip is rotated so that two symmetrically opposed tabs attached to the tip are each received within a recess determined by a shoulder and a locking rib attached to the shoulder, and two diametrically opposed detents extending from the neck are each received within a recess in the bore surface.
