Abstract
In tire chains, closures are required to lock tension-chain lines (10) in the tensioned position. A proposed closure is provided with a pull-through orifice (2) for the tension-chain line (10) and with a locking slot (3) adjacent to the pull-through orifice (2). To prevent the particular chain link (9) suspended in the locking slot (3) from working loose, the pull-through orifice (2) is equipped with an elastic insert (11) which forms at least one engagement cam projecting into the locking slot (3).
Claims22
Closure for tyre chains, including non-skid tyre chains, with a basic body with at least one connecting lug for the end member of a retaining line and with a pull-through orifice having an elastic insert for a tension-chain line, as well as with a locking slot adjacent to this pull-through orifice for locking the tension-chain line, characterised in that the insert (11) overlapping the basic body (1) on both sides by means of retaining shoulders (17, 18) forms at least one engagement cam (13, 14) narrowing the mouth (12) of the locking slot (3), for the elastic clamping of a leg of a chain link (9) of the tension-chain line (10), this leg being introduced into the locking slot (3) by overcoming the engagement cam (13, 14).
