Abstract

A device (51) for locking strands of laces (31, 32, 48), including a hollow body (52) demarcating a cavity (53), the cavity defining at least one passageway (54, 55) for passage of the lace strands (31, 32, 48), the locking device (51) including a locking member (58), the locking member (58) being movable between a locking position and a release position, the locking device (51) operating via cooperation of the locking member (58) with each passageway (54, 55) to lock each lace strand (31, 32, 48) by a wedging effect, an elastic mechanism (59) biasing the locking member (58) towards the locking position. The locking device (51) acts for at least three lace strands (31, 32, 48), and at least one passageway (54, 55) is adapted to receive two superposed lace strands (31, 32, 48).

Description

technical field [0001] The present invention relates to mechanical locking devices for flexible strands such as cords, ropes, threads, belts or any other article of similar appearance.
