Abstract
A releasable tube coupling comprises a body providing a housing in which an annular seal and clamping ring are located and secured by a retainer and, a releaser slidably supported by the retainer for limited axial movement relative to the housing. The seal is of generally Z-section having outer and inner flanges connected by an inclined web convergent towards the inside of the housing. The clamping ring is mounted into the seal and has a plurality of spaced apart radially inwardly directed inclined teeth which overlie the web on the inner face of the seal for engagement with the outer surface of a tube received within the housing to retain the tube in the housing. The teeth are displaced away from the tube to permit axial withdrawal the tube on inwards movement of the releaser which acts on the teeth through the seal web.
