Abstract: In order to create a device for fastening and clamping straps that also permanently withstands high mechanical loads of the type that occur during the tensioning of slacklines, in particular longlines, at least one pair of pivoting levers are be provided, between which two mutually parallel clamping plates with flat clamping surfaces are hinged, the clamping surfaces being at least as wide as the strap and being provided with securing devices for securing the strap in the clamped state. The pivoting levers are fastened to a tensioning device, for example a chain hoist, on actuation of which the pivoting levers absorb the tension and transmit it to the clamping plates so that the clamping surfaces of the clamping plates are pressed together, thereby securely clamping the strap fitted between the clamping surfaces.

Abstract: The invention relates to a device for fastening and clamping straps. In order to create a device for fastening and clamping straps that also permanently withstands high mechanical loads of the type that occur during the tensioning of slacklines, in particular longlines, the invention proposes that at least one pair of pivoting levers be provided, between which two mutually parallel clamping plates with flat clamping surfaces are hinged, the clamping surfaces being at least as wide as the strap and being provided with means for securing the strap in the clamped state. The pivoting levers are fastened to a tensioning device, for example a chain hoist, on actuation of which the pivoting levers absorb the tension and transmit it to the clamping plates so that the clamping surfaces of the clamping plates are pressed together, thereby securely clamping the strap fitted between the clamping surfaces.
