Abstract:
An indicator device for indicating that a set value of a clamping force of a tightenable clamp has been reached, wherein the clamp comprises an approximately C-shaped clamp strip, having first and second circumferential ends facing one another in a circumferential direction of the clamping strip and axial ends extending in the circumferential direction from the first circumferential end to the second circumferential end, wherein the axial ends have radially inwardly projecting end face walls with a radially inner edge, and further comprising clamping jaws connected to the first and second circumferential ends, the indicator device comprising:at least one breakable indicator element for each one of the end face walls, wherein the breakable indicator element is configured to be placed onto the radially inner edge of the end face wall;wherein the breakable indicator elements are configured to break when the set value of the clamping force of the clamp is reached and a predetermined spacing of the radially inner edge of the end face walls from a cylindrical object clamped in the clamp are reached.
