ABSTRACT:
The invention provides a process for securing a rigid coupling member to one end of a flexible pipe which comprises an armouring formed by a metal strip wound with a short pitch around a tubular core.
According to this process this armouring is cut out along a cross-section of the metal strip which is then inserted into a corresponding recess of the coupling member, in which a solidifiable material is subsequently injected.
