ABSTRACT:
Detachable tube assemblies, such as those useful in remote spraying devices, are disclosed. The assemblies use a U-shaped coupling device having a base with a central aperture, flexible arms, and radial extensions. The radial extensions interfit with alignable radial holes on tubes to be coupled together. The central aperture guides and aligns an actuator rod. The rod can be used to remotely actuate a spray.
