ABSTRACT:
An improved auxiliary lock for closing and fastening a movable part to a stationary part using a key is described. The device comprises a bolt assembly comprising an inner cylinder having a key hole and an outer cylinder encircling the inner cylinder, a first re-entrant engagement member to be fixed to the movable part and a second re-entrant engagement member to be fixed to the stationary part. The first and second re-entrant engagement members have holes made therein to be put in alignment when these re-entrant members are nested together with one projection of each engagement member inserted in the indentation of the counter engagement member. The bolt assembly is inserted in the through holes of these re-entrant engagement members when nested, thereby locking the movable part to the stationary part.
