A brassiere closure has a pair of closure parts each having an eye with inner and outer parallel longitudinal webs. A separation plane passes through both of the webs and the slot, and a transverse central plane perpendicular to the separation plane passing centrally through the slot and both of the webs. A bridge extend transversely from the inner web has a planar floor face lying on the separation plane and is formed offset along the separation plane from the transverse plane with a throughgoing latch opening. A hook carried on the bridge spaced has an edge formed of sections directed toward and forming a V-shaped opening with the edge of the bridge. An outer edge of the hook carries a pin engageable in the closed position through a latch opening of the bridge of the other closure part.
