Abstract

A clamp for hoses, pipes and the like which is intended to prevent leakage due to expansion of the clamp by increased internal pressures. The clamp has a clamping band with two ends. When the clamp is installed and in a generally unstressed condition, a projection on one end is spaced from an abutment on the other end. As internal pressure increases, the clamp expands until the projection engages the abutment. Further expansion is prevented.
