  "textContent": "In a clamping device (1) for anti-slip chains, a rotary wheel (4) is formed in a housing (2). Furthermore, a first ratchet wheel (8) with an axial central projection (9) and a second ratchet wheel (10), through which the central projection (9) of the first ratchet wheel (8) is inserted, are mounted, whereby the tensioning cable is received in a circumferential groove (34) of the second ratchet wheel (10). A spiral spring (40) is connected with its inner end (18) to the central projection (9) and with its outer end (19) to an inner circumferential surface of the second ratchet wheel (10). Via the rotary wheel (4), the user rotates the central projection (9) of the first ratchet wheel (8) for tensioning, whereby the tension building up in the spiral spring (40) leads to a co-rotation of the other ratchet wheel (10) and thus to a build-up of tension in the tensioning cable. Two locking pawls (14, 15), each of which can engage with one of the two ratchet wheels (8, 10), are held in engagement with the ratchet wheels (8, 10) via an actuation device during tensioning and block these against the tensioning direction. For disassembly of the anti-slip chain, both locking pawls (14, 15) are swung out of their engagement positions via the actuation device, whereby the tensioning cable is released for relaxation.",
