Description
Designed to prevent accidental disconnection of pipework from standard push-fit fittings. It provides an additional layer of mechanical security by locking beneath the collet, stopping the release mechanism from being depressed unintentionally. In busy pub cellars and bar installations, pipework can be subject to movement, vibration and handling during maintenance or cleaning. Fitting a locking clip reduces the risk of accidental pipe release, helping protect beer lines, gas feeds and beverage supply systems from disruption.
The clip is quick to install and remove, simply snapping into position under the collet after the tube has been inserted and secured. It does not interfere with flow performance or sealing, but adds reassurance in high-traffic or exposed installations. Suitable for use with standard John Guest push-fit fittings only, the locking clip is available in sizes up to 1/2" to match common drinks dispense tubing dimensions.
