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.

[ What is claimed is:] [2.] A syringe for dispensing two viscous materials as an admixture, comprising a body and a mixing tip:the body comprising a double-barrel assembly having juxtaposed first and second barrels having a common length and a generally cylindrical bore of a common diameter, each barrel bounded at a discharge end by first and second shoulders, respectively, each shoulder having a generally planar surface, the surfaces coplanar and contiguous, a generally cylindrical neck extending from and symmetrically disposed between the shoulders, the neck including first and second outlet passages in fluid communication, respectively, with the first and second barrels, each barrel at an opposite end circumscribed by a common finger-grip closely receiving within said bore a piston;the body further comprising a double-plunger assembly having juxtaposed first and second plungers of a common length, each plunger extending at a proximal end in an end-piece rigidly attached to one of said pistons, and at a distal end rigidly attached to a common thumb-rest;the body further comprising a first mating assembly having diametrically opposed first and second detents extending outwardly from the neck, and opposed first and second locking ribs symmetrically disposed with respect to said neck and rigidly attached, respectively, to said first and second shoulders, each rib having a plurality of generally planar locking faces generally parallel to and at a common predetermined distance from said shoulder surface;the mixing tip having an inlet end and a discharge end and a bore therethrough, the bore having a generally cylindrical portion at the inlet end and extending in a conically tapered portion toward the discharge end, said cylindrical portion determined by a circumferential surface adapted to closely receive said neck, a static mixing element being closely received and wedged within the tapered portion;the mixing tip having at the inlet end a second mating assembly having opposed generally planar, arcuate first and second locking tabs of a common predetermined thickness less than said first mating assembly predetermined distance, each tab having at least one edge beveled at a common predetermined angle, the tabs symmetrically disposed with respect to said cylindrical bore portion, said circumferential surface having diametrically opposed first and second detent recesses and first and second ramps contiguous at a proximal end, respectively, to said recesses, the first and second mating assemblies conjoining when the neck is inserted into the cylindrical bore portion in a relative orientation such that each detent contacts a ramp distal end, thereby determining an engaged configuration, the mating assemblies interlocking when the mixing tip is rotated in a first direction until each detent, traversing the ramp and reaching the ramp proximal end, is received within a recess, and each tab is closely received between one of said pluralities of rib locking faces and a shoulder, the mating assemblies detachable when the mixing tip is rotated in the opposite direction until the neck and cylindrical bore portion are in said engaged configuration.
