Abstract
An indicator device is provided for indicating that a set value of a clamping force of a tightenable clamp has been reached. The clamp has an approximately C-shaped clamp strip with 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. The axial ends have radially inwardly projecting end face walls with a radially inner edge. Clamping jaws are connected to the first and second circumferential ends. The indicator device has at least one breakable indicator element for each one of the end face walls, wherein the breakable indicator elements can be placed onto the radially inner edge of the end face wall. The breakable indicator elements 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 is reached.
