The invention provides an improved plastic socket component of the female snap of a snap fastener, which socket component is attached to one face of a flexible sheet such as the cloth of a garment by means of a rivent driven in from the other face of the flexible sheet and includes a cavity for coupling and uncoupling with a projection formed on a male snap. The cavity is surrounded by a thick peripheral wall having a plurality of relatively long arcuate embossments arranged at small intervals in the peripheral direction on an upper inner surface portion of the wall and a plurality of arcuate slits substantially equal in length to the embossments and arranged outwardly opposite thereto, the slits extending vertically through the peripheral wall. Adjacent pairs of the slits are interposed by thick wall portions having high rigidity. According to the improved construction, coupling and uncoupling between the projection of the male snap and the cavity of the female snap are carried out with a constant force regardless of the thickness of the flexible sheet, and do not get too tight temporarily after washing the flexible sheet. |
