Abstract: A safety belt buckle for receiving and retaining a tongue includes a housing defining a path therein to receive the tongue. A main locking element is movable between a release position in which it does not engage the tongue, and a locking position in which it engages the tongue to retain the tongue in the buckle. A push button is movable along a longitudinal axis of the path and is positioned above the main locking element. A second locking element is mounted to the housing between the push button and the main locking element, and includes a first portion engagable by the push button, and a second portion movable to a first position to engage the main locking element to prevent movement of the main locking element to the release position. The second portion and the push button are movable along the longitudinal axis of the path in opposite directions when the main locking element is to be released so that the second portion is moved to a second position in which the main locking element is freed.
