Cierre para bolsos y similares, caracterizado esencialmente por constar de una placa dotada de vértices redondeados definiendo una caja elemental y aplanada, sujeta, por sus extremos mediante sendas pestañas enfrentadas al cuerpo del bolso, asegurándose la fijación mediante una placa de su misma forma situada en la cara posterior, por la que sobresalen las pestañas mencionadas, quedando dobladas en ángulo recto en disposición enfrentada, con sujeción rígida de la placa, la cual, en su parte central comporta una pieza hueca en forma de cuerpo de revolución y estructura de bulbo, obtenida por conformación de una lámina metálica y formando en la cara interior de la placa un reborde a base de unos apéndices terminales doblados en forma de brazos opuestos que permite, además de la sujeción segura del, elemento su giro axial, en tanto que el otro extremo de la pieza hueca forma una expansión transversal susceptible de recibir y retener los extremos enfrentados de un elemento anular de funciones enclavadoras y de bloqueo del dispositivo.
