ABSTRACT:
A hose fitting wherein the free end of a nipple or pipe is sealingly held in one end portion of a hose by a sleeve having a tubular body with a single axially parallel slot and one or more bridges extending across the slot at the exterior of the tubular body. The latter has depressions which extend toward the nipple or pipe to urge the end portion of the hose into sealing engagement with the nipple or pipe. The sleeve can be detached from the end portion of the hose by partially or fully destroying, by deforming or by removing the bridge or bridges so that the slot can be widened prior to separation of the sleeve from the hose.
