An escape ladder of collapsible construction has links (51) interconnecting adjacent rungs (53) with one end of the ladder being provided with means for fixing the ladder to a structure such as a wall. At least one end of each link is arranged for movement relative to its respective rung in a direction axially of the rung between a first position in which the link is able to pivot relatively to the rung and a second position in which the relative pivotal movement is prevented. The fixing means (3) has structure engaging elements (11, 13) and means for varying the distance between these elements according to the width of the structure to which the ladder is to be fixed. |
