[0001] The invention relates to a breakdown repair kit with a detachable connecting element and to a system comprising such a breakdown repair kit and a sealant bottle. Furthermore, the invention relates to a method for replacing a connecting element and to a fixing element for fixing a connecting element to a breakdown repair kit.

[0002] Tire repair kits are known in the art and are typically used to connect the kit to the vehicle tire or tire valve via a hose. A tire repair kit usually includes a compressor for generating compressed air, which is used to pump a sealant into the tire in the event of a puncture and / or to inflate the tire after sealing. Tire repair kits can, for example, be designed in two parts. In two-part kits, the sealant bottle is connected to the compressor via a connector.

[0003] A disadvantage of such breakdown kits is that the connection element for the sealant bottle on the compressor is not designed to be replaced. This is problematic because the connection element becomes contaminated with sealant after use, making multiple uses difficult.

[0004] This is where the present invention comes in. The object of the invention is to provide an improved breakdown kit, a system comprising a breakdown kit and a sealant bottle, and a method for replacing a connecting element in a breakdown kit, by which multiple uses of the breakdown kit can be ensured.

[0005] Furthermore, the object of the invention is to provide a fixing element by which a connecting element in a breakdown kit can be replaced more easily, thereby ensuring multiple uses of the breakdown kit.

[0006] The object of the present invention is achieved by a tire repair kit for sealing and inflating vehicle tires, comprising the features of claim 1, and by a system comprising the features of claim 8.
