Abstract
An improved stab-type coupling of the type used for connecting an end portion of a smooth wall non-metallic pipe or tube to fittings or other pipes or tubes wherein the coupling body has a first end area including an internal recess adapted to receive the end portion of a smooth walled non-metallic pipe. An elongated hollow insert is disposed within the recess for receiving the pipe end portion axially thereover. At least a pipe gripping member is disposed within the recess in a radially spaced surrounding relationship with a portion of the insert to retainingly engage the pipe end portion as it is inserted axially therepast. The improvement comprises a closing structure associated with the body first end area for closing the recess and thereby protect the coupling interior. The closing structure accommodates selective removal of a portion thereof from the body to expose the recess prior to receipt of a pipe end portion thereinto. The accommodating portion may comprise any convenient arrangement such as a frangible zone, a designated cutting area and the like. The closing structure may be comprised of a separate, removable end cap.
