Abstract
A pop-up sprinkler has a sprinkler housing containing a pop-up spray nozzle assembly springably biased to a retracted position. Upon supply of water under pressure to the housing, the assembly pops up to an elevated position to provide an irrigating water spray in a selected direction. A clamping collar prevents rotation of the elevated spray nozzle assembly with respect to the housing.
