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.
Claims19
A spring band clip comprising an annularly bent spring band having a central portion, a first end portion and a second end portion, wherein the end portions overlap in a stressed condition and in an unstressed condition in an overlap region, and associated with each end portion is a clamping jaw which is peripherally disposed between the central portion and the clamping jaw of the respective other end portion, the first end portion having a projection which, at least in the tangential direction, is provided to engage an abutment on the second end portion, such that, when the clip is clamped fast on a hose, engagement of the projection on the abutment substantially prevents expansion of the spring band clip caused by internal pressure.
