Abstract: A pipe attaching apparatus is used to attach pipe, electrical conduit and the like to a channel support without the use of tools. With one hand, an installer holds the apparatus containing a pipe between two clamp halves, squeezes a pair of base plates together, inserts a pair of hooks into a support channel and releases the base plates so that the hooks engage inturned flanges in the support channel. Using the same hand, the installer locks the apparatus by engaging a pair of locking pins on a cam in holes in the base plates. The cam in a locked position gives a visual indication of successful installation.
