Abstract
A pipe-encircling steel shield includes integral bands with inclined slots for engagement with screw-type tightening elements. The shield compresses a gasket or packing member against the pipe ends to be coupled. This structure reduces the number of parts in comparable couplings by about one-half. The shield area preferably includes longitudinal slots which trap gasket material during tightening, facilitating use with irregular pipe sections.
