Abstract: A coin handling construction including a housing provided with a cap for closing access to the interior of the construction. Locking means are provided for securing the cap in place on the housing. These locking means comprise a rotatable rod positioned within the housing. First locking elements are mounted on the cap, and second locking elements are mounted on the housing. The locking elements define a surface for inter-engagement of the elements which prevents separation of the cap and housing. The rod is rotatable between a first position for maintaining the locking element surfaces in the engaged condition, and a second position which frees the cap for separation from the housing.
