Abstract
A pyrotechnic releasable locking device for maintaining a first and a second member of a structure in a fixed relationship. The locking device comprises a body for locating on or within the first member of the structure such that, in use, a part of the body protrudes into the second member of the structure. The pyrotechnic compound is located on or within the body and a channel is located in the interior of the body and runs between the pyrotechnic compound and an exterior surface of the part of the body that, in use, protrudes into a recess in the second member of the structure. When the pyrotechnic compound is ignited the combustion gases travel along the channel into the recess of the second member of the structure, and the resultant gas pressure forces the body out of the recess thereby releasing the second member of the structure.
