The fluid section or head (10) for a plural component applicator can be easily assembled or removed from the air section (12) by turning the fluid head ⅛ of a turn. The fluid head (10) has four tabs (14) that protrude and engage with four undercut features (16) within the handle (12). Tabs (14) are inserted through corresponding openings (16) in the front (12a) of air section (12) and rotated such that tabs (14) are retained behind lips (18). A locking tab feature (20) in the hose manifold (24) mates to a recess feature (22) in the handle (12) to prevent the fluid section (10) from rotating.
