A push button lock for a safety belt is described including a first lock part which has an insertion aperture at one end, and a second slide in tongue part which is insertable into the opening in an axially extending plane of the first part. Within the first part there is a receiving housing which includes a web portion with a side wall on each side edge of the web portion which latter has a fixed stop which is engageable on a transverse edge formed on the tongue. A slot is provided in each side wall of the receiving housing and this has a first part which is parallel to the axial plane and a second part inclined with respect thereto. The housing has a push button which is axially slideable therein and this comprises a cross-bar, two side walls which are spaced apart by the cross-bar and a manually actuable portion at the insertion opening end of the lock part. When one presses the manually actuable portion, two elements, which can be part of the cross-bar, slide in these slots to lift the push button so that the cross-bar is raised to release the tongue portion so that the transverse edge can be disengaged from the stop. |
