Abstract
A device for opening and locking a tail unit is provided. The tail unit includes a body and at least one fin, pivotable relative to the body along a first axis, that has a projection that forms an element. The device comprises a control ring, slidable relative to the body along a second axis, that includes a component, forming an element, that bears against the projection to deploy the fin, the second axis being non-parallel and non-secant to the first axis. A means for shaping one of the elements during translation along the second axis of the control ring towards the projection of the fin is provided on the other element. The body includes a bearing surface to support the fin during shaping, in which the support of the fin on the bearing surface corresponds to the deployed position of the fin.
