Abstract
The catch comprises a bolt (22) having a locking body (24) and means for clipping the body (24) into a keeper (28) by clamping the keeper (28) between a bearing bush (54) and at least one retractable locking ball (56). The bearing bush (54) is mounted to slide axially around the locking body (24), being moveable, by cooperation with the keeper (28), against a return spring force, from a position releasing the bolt (22), in which the bush (54) covers the locking ball (56), holding it in the retracted position, to a position locking the bolt (22), in which the bush (54) and the locking ball (56) grip the keeper (28). The bolt (22) further includes safety means (80) preventing accidental displacement of the bush (54) from its bolt releasing position to its bolt locking position other than by cooperation of the bush (54) with the keeper (28).
