Abstract: A hydraulic line coupling, for a hydraulic brake or clutch of handlebar-operated vehicles, having a line connection piece with a hydraulic line extension and a housing with a coupling opening, in which the line connection piece for coupling the line to the housing can be disposed. The connection piece comprises a passage connected to the line. A valve device is disposed in the housing and is configured such that the valve device closes the connection for the connection piece when the connection piece is not in the coupling opening. The line coupling has a seal, with which seal the valve device closes the connection for the connection piece when the connection piece is not in the coupling opening. With the seal, the connection piece seals the passage from the environment when the connection piece is in the coupling opening.

Abstract: A braking system is proposed for a vehicle, in particular a lightweight vehicle, in particular a pedal cycle, comprising a brake device, a mechanical urging device, and a hydraulic urging device, wherein the mechanical urging device and the brake device form a parking brake device, and the hydraulic urging device takes the form of a hydraulically actuable release device for the parking brake device.

Abstract: A hydraulic line connection for a hydraulic brake of vehicles with handlebar steering comprises a line-fastening device, which has a fastening portion for fastening the line-fastening device in a support of a hydraulic component of the hydraulic brake and a connecting portion for connection with a hydraulic line, wherein the line-fastening device has an extension, which is attached to the fastening portion on the side opposite to the connecting portion.
