Claim:
1. An underwater connecting apparatus comprising: a flexible diaphragm that defines a wall of a chamber, the wall comprising an outer perimeter with a first non-circular profile and an inner perimeter with a second non-circular profile when the chamber is viewed in a cross-section perpendicular to an axial extension of the flexible diaphragm; at least one groove on the outer perimeter configured to move outward, the at least one groove at least in part defining the first non-circular profile of the outer perimeter; wherein the chamber is configured to comprise a fill material, the wall of the chamber surrounding the fill material in the cross-section; wherein the outer perimeter of the wall with the first non-circular profile has a wave-shaped profile, the wave-shaped profile having a plurality of wave peaks, at least one wave peak of the plurality of wave peaks having a first curvature that is different than a second curvature of at least one other wave peak of the plurality of wave peaks; and wherein the first non-circular profile of the outer perimeter is configured to allow a volume of the chamber to change without changing a length of the outer perimeter.
