Abstract: An adjustable two part belt with locking means comprises elongated belt members which overlap each other and transverse members connected to the ends of the overlapping portions of the belt members and at least partially encircling the corresponding portions of the belt members. At least one of the transverse members includes a clamp means in the form of a metallic strip which encircles at least a portion of the overlapping belt members and which is bendable to clamp the overlapping portions of the belt members against each other to maintain the length adjustment of the belt. The metallic strip means is preferably in a C-shape.
