ABSTRACT:
A safety belt buckle has a slider having first and also second parts each adapted to engage and retain a locking member in a locking condition in which it engages a tongue inserted in the buckle. The slider is spring biassed to a position in which one part engages and retains the locking member and is movable against the spring bias to a second position to permit the locking member to move to release the tongue. The arrangement is such that if the buckle is subjected to a severe force, which moves the slider against the spring bias, the slider moves to a third position in which the second part engages and retains the locking member in the locking position.
