Abstract
A method for hooking a flexible envelope to a fastener device, comprising employing an annular and rigid fastener (2), provided with an annular groove (3) on its outer peripheral side, tightening the sheath at the fastener (2) and locking it in place in such a manner that it assumes the shape of the groove (3) by means of a tightening collar (4) comprising a cable made of a substantially inextensible material of high tensile strength and wound inside said groove to a specific height within it, and placing an annular seal (5) in contact with the outer peripheral side (4a) of the tightening collar (4), whereby this seal (5) when compressed may deform radially in order to provide the tightening collar with a degree of freedom with respect to the groove sidewalls (3a); and a hooking device for use with the method.
