Abstract
A device for crimping or coupling end elements of a flexible pipe. The pipe includes a metal carcass of a helically wound wire wherein the winding provides gaps between adjacent windings. A sealing sheath outward of the carcass. The device comprises a cylindrically shaped tubular nipple that fits over the carcass with a tapered first conical leading end that is insertable between the sealing sheath and the carcass. The nipple has over a portion of its external surface grooves which substantially match in shape the squeezed out or crept parts of the sheath such that after the nipple has been installed at least part of the squeezed out crept parts of the sheath are almost completely housed in the grooves of the nipple.
