A common method of retaining spray nozzles in texture applicators is to capture the nozzle by a rubber cap which is stretched over a retaining flange on the applicator's sprayhead. The effort required to stretch an elastomeric nozzle retainer (cap) 10 over the retaining flanges 12 on the sprayhead 14 is reduced by providing features facilitating the use of a prying tool 16 to amplify the user's effort. Flange relief flats 18 accommodate the natural, temporary inward deflection of the cap 10 during installation.
