Abstract
Abstract First and second portions of a chin strap of a helmet are respectively connected to first and second engaging members of a buckle connector. The first engaging member includes a projecting portion and the second engaging member includes a pair of pivotal claws for engaging the first engaging member. A spring acts on the claws to urge the claws to an operative position in which the first engaging member is engaged by the claws. The first engaging member is guidably engaged by side walls on the second engaging member in the course of engagement and disengagement with the claws to restrict lateral movement of the first engaging member.
