Abstract
A fitting has an external body and a caliper element, lodged in an axial cavity of the body and able to block the end of a tube inside the cavity. The caliper element can be moved from a rearward position blocking the tube, to a forward position releasing the tube, and includes a flanged rim protruding from an end of the body. A security ring is joined to the end of the body from which the flanged rim protrudes. The ring has an outer portion which extend axially from the end and can resist at least an axial force exerted manually, and an innermost portion which is flexible so that when subjected to an axial force exerted manually, it can move axially and to touch the flanged rim. The inner and outer portions are reciprocally positioned so pressure can be exerted on the innermost portion only with a special tool.
