In a tube coupling of the kind having a collet for gripping a tube within a body member, the collet having arms co-operating with a tapered bore in the body member so that a pull on the tube pulls the collet outwardly and so causes the collet arms to grip the tube more firmly, and wherein the tube can be released from the coupling by axial inward pressure on a head on the collet, accidental release of the tube is prevented by an end cover through which the tube passes and which surrounds the collet head, the end cover resiliently engaging in the body member.
