Abstract
Abstract A deep ocean submersible including a pair of glass shells which are adapted to mate with one another about their rims to form a submersible hull; each shell having a peripheral lip which extends outwardly from the rim thereof; an elastomeric band mounted to each respective lip; and means for clamping the bands so that the shells can be tightly retained along their rims.
