Should the need arise to demount the connection unlock the nut and push the collet towards the body of the fitting and pull the pipe to release.

Review: Quick and easy - It work great, very easy to use, don't leak has a right seal, whould recomend.
Review: Great product, but customer returned contaminated parts. Suggest you find alternate supplier - The product by John Guest is fantastic, deserving five stars. BUT -- someone returned some of these connectors after using them for a strong-smelling oil, maybe car deodorizer. Could not get the stuff washed off my hands after opening the first package. Planned to use this on a drinking water line, but not with this contamination. Got a free replacement with the same problem. Giving up and buying elsewhere. In the attached photo, note the smeared printing on the package. The oil dissolved the package label. Nasty stuff.
