Abstract
A dual purpose stopper having a deformable, resilient body resides in a branch, communicating with a pipe through an opening in the wall of the pipe. The stopper has a distendable rear portion which can be expanded radially to seal the branch, allowing removal of a mechanism used to actuate the stopper. When actuated, the stopper is shifted by the mechanism from the branch into the pipe, deforming the stopper and sealing the pipe.
