Abstract: A fastening assembly includes a bolt; a support for the bolt, the bolt being movable relative to the support between an extended position and a retracted position; and a keeper with which the bolt is engageable when in its extended position. The keeper comprises a keeper element and the bolt affords a formation able to receive and retain the keeper element. The bolt comprises portions movable relative to one another to permit the keeper element to enter the formation as the bolt is moved from its retracted to its extended position. Relative movement between the bolt portions is prevented when the bolt is in its extended position, whereby the keeper element is held retained in the formation.
