The invention involves a keeper () to interact with a bolt () of a lock (); The keeper includes a bracket () for attachment to a structure, and a keeper rod () secured to the bracket, the keeper rod extending from one surface () of the bracket. In the keeper, a shaft () is attached to the bracket and can rotate freely relative to the bracket such that it extends in a longitudinal direction (X); a blade () is mounted on the shaft () on one side of the bracket near the keeper rod in such a way as to always rotate along with the shaft; an angular position indicator () is also mounted so as to always rotate along with the shaft; the blade being so positioned that it can be rotated by the latch when the latch hooks on to or releases from the keeper rod, and the angular position indicator () being capable of indicating the angular position of the blade. The invention is for example intended to be used on an aircraft door such as that of a helicopter.

The present invention relates to a locking device (), comprising a threaded rod () and a tapping tube (), which are movable relative to each other. An outer surface of the tube includes a first anti-rotation form. The device further comprises: a locking sleeve () positioned around the rod and comprising a second anti-rotation form () capable of being assembled to the first anti-rotation form; and an elastic element () connected to the locking sleeve. In a locked position, the first () and second () anti-rotation forms are assembled; and in a release position, said anti-rotation forms are axially spaced apart, whereby the tube is free to rotate relative to the sleeve.
