A tightenable band clamp with a clamping band and a tightening head with two clamping jaws which are a certain circumferential distance apart and which can be moved toward each other by a tightening device. For this purpose, at least one clamping jaw, in the area of its radially inside surface, has at least one projection which extends in the circumferential direction toward the other clamping jaw and which projects into the gap.

Tightenable band clamp

A pipe clamp for connecting two partially insertable pipes has a clamping strap that is placed circumferentially about the spherical end sections of the pipes inserted into one another. The clamping strap has two outwardly projecting clamping jaws provided with a hole through which a clamping screw extends. The clamping strap is curved about a transverse axis that is positioned for coaxially inserted pipes in the untightened state of the clamping strap in a central plane of the clamping strap extending perpendicularly to the coaxial center axes of the pipes at a spacing from a center of the spherical end sections of the pipes. The inner radius of the clamping strap in the untightened state is smaller than the outer radius of the spherical end sections such that the sum of the spacing and of the inner radius is greater than the outer radius of the end sections.
