A portable lock for preventing a door from being opened from the outside. The portable lock has a body formed from two symmetric covers with two spring-biased pivoting handles and a slidable adjustment rod protruding from the assembled body. The adjustment rod has a plurality of holes along its length and an engagement member at an outer end. The engagement member is adapted to engage the strike of a door jamb. The length of the rod is adjusted so as to position the body of the portable door lock firmly against an inner side of the door and jamb. The handles are operated by a user to adjust the length of, and to lockingly engage the adjustment rod with protuberances provided at an inner end of the handles. The portable door lock can be adjusted to different door thicknesses. The handles can be additionally secured against pivoting by the insertion of a U-shaped member into the body of the portable lock.
