A device for fastening a flexible tie has a hollow body provided with a guiding channel that forms a funnel for a translationally movable blocking element, this blocking element being subject to the constant action of an elastic element. The hollow body is housed in a case where it can move translationally parallel to the blocking element, and the blocking element is maintained in the case, on one side by virtue of the elastic element that acts directly between the blocking element and the case, and on other side by virtue of an abutment. A retractable abutment makes it possible to retain the hollow body against the blocking element to block the tie, or to release this hollow body so as to enable the sliding of the tie. The fastening device is particularly adapted to ensure the adjustment of a garment or a shoe by means of a tie, such as a lace.

1. A device for fastening a flexible tie, said device comprising:a hollow body provided with a guiding channel, said channel forming a funnel, a blocking element is positioned for translational movement in the funnel subject to the action of an elastic element, the elastic element pushing the blocking element into the funnel where the tie passes, in view of blocking the latter when it is biased to slide in the same direction as the blocking element, and of enabling it to slide in the opposite direction against the thrust of the elastic element; the hollow body being housed in a case, the hollow body being translationally displaceable in the case parallel to the blocking element; and the blocking element being maintained in translation in the case, on one side by means of the elastic element acting directly between it and the case, and on the opposite side by means of an abutment carried by the case, a retractable abutment being provided on the case so as to retain the hollow body under pressure against the blocking element and the interposed tie, in a first position, and to leave the hollow body free in translation with respect to the case and the blocking element, in a second position.
