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).
A catch comprising a bolt (22) having a generally cylindrical locking body (24) and means for clipping the body (24) into a keeper (28) by clamping the keeper between a bearing bush (54) and at least one retractable locking ball (56) carried by the locking body (24), the bearing bush (54) being mounted to slide axially around the locking body (24) and 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 including 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);
A catch comprising a bolt (22) having a generally cylindrical locking body (24) and means for clipping the body (24) into a keeper (28) by clamping the keeper between a bearing bush (54) and at least one retractable primary locking member (56) carried by the locking body (24), the bearing bush (54) being mounted to slide axially around the locking body (24) and being movable, by cooperation with the keeper (28), against a return spring force, from a position in which the bolt (22) is released and in which the bush (54) covers the primary locking member (56) and holds it in the retracted position, to a position in which the bolt (22) is locked and in which the bush (54) and the primary locking member (56) grip the keeper (28), the bolt (22) further including a secondary locking member (82) actuable by a drive member (84) which is substantially axially slidably mounted on the locking body (24) between an operative position, in which said secondary locking member (82) immobilizes the bearing bush (54) in the position covering the primary locking member (56), and a stand-by position in which said secondary locking member allows the bearing bush (54) to slide along the body (24).
