1. A slider for zip fasteners comprising:
a slider body comprising a first end at which two longitudinal sliding channels for teeth of a zip fastener open and a second end at which a single longitudinal sliding channel for the teeth of the zip fastener opens, the two channels joining in said single channel in said slider body;
a lock mechanism of the sliding of the slider positioned in the slider body and comprising a movable stop element of the sliding of the slider in a longitudinal direction and in an opening direction of the zip fastener;
a release button of the lock mechanism, slidably mounted in the slider body and manually operable to unlock the lock mechanism;
wherein the slider lacks any operating pull tab configured to interact with the lock mechanism; and
wherein the release button is configured to cooperate with the movable stop element of the lock mechanism and move the movable stop element from an operative position,
wherein the movable stop element engages one of said channels for locking a sliding of the slider along an opening direction of the zip fastener, to a non-operative position wherein the movable stop element does not engage any of said channels.
