Abstract
Abstract An end attachment for a watch band for use with a wrist watch provided with customary spring bars. The end attachment includes an adaptor which comprises a plate-like member with a generally tubular member at one end adapted to axially receive a spring bar of a watch and a transverse generally rectangular opening through the plate-like member substantially parallel to and adjacent to the tubular member. It also includes a clasp-supporting member, means for securing it to the end of a watch band and clasp means pivotally connected to the clasp-supporting member. The clasp means includes a resilient flange. To assemble the end attachment, the resilient flange and the part of the clasp means which extends outwardly from the pivotal connection are passed through the rectangular opening and the clasp means is then moved about its pivotal connection until the resilient flange forms a snap fit with a portion of the clasp-supporting member, in which position the end attachment is fully assembled. The user may easily remove the end attachment from an adaptor which has been mounted between the lugs of his watch by merely opening the clasp and withdrawing its outwardly extending part and its resilient flange through the rectangular opening of the adaptor. Consequently the user can change watch bands used with his watch to coordinate his watch band with the clothes to be worn or he can remove his watch band to clean it, without the help of a jeweler.
