Abstract
A fastening device of the invention is formed of two fastening members. Each fastening member has a flat base portion, and a plurality of engaging projections fixed on the base portion laterally and vertically. Each engaging projection has at least one leg fixed to the base portion at one side and an engaging head portion fixed to the other side of the leg. The engaging head portion has a lateral size greater than that of the leg. Non-engaging projections are integrally formed on at least one of the fastening members. Each non-engaging projection has a height less than the engaging projection. In case the two fastening members are engaged, when one engaging projection projecting toward one non-engaging projection is pushed laterally by another engaging projection situated adjacent to the one non-engaging projection, an engaging head portion of the one engaging projection is pushed toward the one non-engaging projection and then is returned to an original portion by the one non-engaging projection to thereby engage the engaging head portions of the one and another engaging projections. Thus, the fastening members can be easily fastened and separated repeatedly.
