1. A method for splicing two bundles of multifilament textile fibers comprising:
inserting an end portion of a first bundle into a first end of a heat-shrinkable sheath and inserting an end portion of a second bundle into a second end of the heat-shrinkable sheath, axially opposite the first end, until ends of the end portions of the first and second bundles are facing each other;
inserting a curable organic material inside the heat-shrinkable sheath in a space separating the end portions of the first and second bundles so as to join the end portions of the first and second bundles together by means of a joining portion, the curable organic material being inserted into the space existing between the ends of the end portions of the first and second bundles after the bundles have been placed inside the heat-shrinkable sheath;
heating a portion of the heat-shrinkable sheath surrounding the joining portion to a predetermined temperature;
curing the curable organic material; and
removing the heat-shrinkable sheath.
