Abstract

A spring band clamp is comprised of an annular spring band having a first end portion and a second end portion. Each end portion has a clamping jaw that projects beyond a periphery of the spring band. The first end portion has a tongue extending radially outwardly from a U-shaped incision in the first end portion. An abutment is formed by a radial inner edge of a free end surface of the tongue. The second end portion has a slot extending in a circumferential direction. The first end portion projects through the peripheral slot in the second end portion. The clamping jaws extend substantially tangentially relative to the circumferential direction of the spring band. The spring band exerts a closing spring force, which is directed in the circumferential direction. The closing spring force is greater in an open position of the spring band clamp than in an operative position. In the open position of the spring band clamp, a support surface of a free end of the clamping jaw of the second end portion bears, due to the closing spring force, against the abutment of the tongue. The support surface is disposed at an angle with respect to a radius of the clamp that intersects with a radial in…
