A snap assembly adapted to receive a cooperating buckle element is disclosed in which a base is provided having oppositely disposed front and rear ends with upper and lower surfaces intermediate the ends, and a hook is integrally formed with the front end of the base and extending inwardly in the direction of the rear end and terminating in a distal end. The hook having an inner surface bounding one side of the hook facing the upper surface of the base for forming an enclosure for receiving the buckle element therein. A flexible locking member is adapted to be moved relative to the inner surface of the hook, with the locking member having an outer end and an oppositely disposed free end. The outer end formed by a wall having one surface thereof extending in overlapping relationship with and secured to the base. Resilient means for continuously urging the free end of the locking member into abutting pressural engagement with the inner surface of the hook and being movable toward and away from the inner surface is provided. The resilient means comprises a rib integrally joined by an arcuate configuration at one end thereof with the wall and extending upwardly therefrom, and a clip integrally joined by an arcuate configuration at one end thereof with the other end of the rib. The clip terminates in the free end of the locking member and is inclined upwardly relative to the base for movement relative thereto. The movement of the locking member provides an angle of deflection in the clip and in the rib so as to obtain a relatively large translation of the free end of the locking member while maintaining a relatively low stress concentration in the locking member by distribution of the stress in each of the arcuate configurations.
