An interlocking closure fastening device comprising an omega-shaped closure element and a co-acting closure element having a trident profile configuration. The co-acting closure element has a profile portion comprising three generally parallel arm portions. The first arm portion terminates in a hook portion, the second arm portion is a generally straight structure having at least one enlarged portion located anterior to its extremity, and the third arm portion terminates in a funnel portion. The closure device is adapted for use with reclosable plastic freezer storage and cooking bags to provide drip-proof and leak-proof seals.
