ABSTRACT: This invention relates to an internal expansion coupling, having particular utility in joining together two tubular members or pipes aligned in end-to-end relationship. The device hereof comprises a) an elongated open ended tubular joint member formed of a relatively rigid sheet-like member, where the sheet ends overlap such that the end portions lie contiguous with each other; b) a continuous sleeve formed of an elastomeric material and overlapping the sheet side about at least one open end of said tubular joint member, where said sleeve, about the circumference thereof, is provided with at least one continuous upstanding rib which is adapted to lie adjacent to and be compressed against the inside wall of a tubular member; and c) means for expanding said sheet-like member whereby said sheet ends move circumferentially towards one another urging said elastomeric sleeve and said rib against the inside wall of a tubular member. Additional features thereof include a particular angular relationship for plural ribs, and the use of such device in providing a T-joint between tubular members.
