<p>A securing arrangement so executed as to be tripped for release on actuation for the purpose of changing the state of an attached item of equipment. It is so executed as to secure the equipment by means of a loadable link (8) in a securing position. The equipment can be released by means of a tripping arrangement (36, 37, 42) by breaking the link by the actuation of an actuating arrangement (20, 32) by means of a specific factor such as a change in pressure. The link consists of a device which is capable of being cut through, such as a cable (8). The tripping arrangement comprises a blade (36, 37) provided with an edge so arranged as to be moved by the effect of the force of a tensioned spring (42) into a position in which the cable is cut through. The actuating arrangement (20, 32) is so arranged as to hold the blade in its first position by means of a locking arrangement (26), and as to release the blade so that it will adopt its second position upon actuation by means of said factor.</p> |
