<p>A pyrotechnic releasable locking device for maintaining a first (25) and a second (33) member of a structure in a fixed relationship. The locking device comprises a body (27) for locating on or within the first (25) member of the structure such that, in use, a part of the body (27) protrudes into the second member (33) of the structure. The pyrotechnic compound (20) is located on or within the body (27) and a channel (39) is located in the interior of the body (27) and runs between the pyrotechnic compound (29) and an exterior surface (41) of the part of the body (27) that, in use, protrudes into a recess (43) in the second member (33) of the structure. When the pyrotechnic compound (29) is ignited the combustion gases travel along the channel (39) into the recess (43) of the second member (33) of the structure, and the resultant gas pressure forces the body (27) out of the recess (43) thereby releasing the second member (33) of the structure.</p> |
