A device for blocking at least one strand of a lace or cord, including a hollow body, a blocking member, and a control member. A cavity of the hollow body defines a housing of the blocking member. The control member allows biasing the blocking member for a displacement in a direction for blocking or unblocking the strand. A reversible locking mechanism in a stable manner retains the control member in a position for unblocking the strand.
