Clasp device for wearable

A clasp device, preferably adapted for use with a wearable device, comprising:

• a main portion, preferably configured to be resiliently bendable and/or deformable in its height direction, length direction, and/or width direction;
• and
• at least one resiliently bendable and/or deformable arm or end extended from the main portion along a curvature and configured to be switchable between a normal state and a deformed state;
• wherein in the normal state a free end of the deformable arm/end is separated from an opposed end of the main portion a first distance and configured to form a first cavity or passage with the main portion for receiving/locking or engaging with an external wearable device, preferably an engageable portion of an associated wearable device, and mounting the clasp device in place, and preferably on the wearable device including a watch and a bracelet;
• while in the deformed state, the free end of the deformable arm/end is resiliently deformed to enable it to be separated from the opposed end of the main portion a second distance relative large in magnitude than the first distance and configured to form by expanding temporarily the first cavity or passage into, a deformable second cavity or passage, having an enlarged dimension than the first cavity or passage, with the main portion preferably for enabling insertion or removal of the external wearable device, preferably the engageable portion of the associated wearable device, into or from the clasp device;
• wherein the deformable arm or end is arranged on or integrated with a clasp portion connected or integrated with the main portion, wherein the clasp portion is preferably an elongated and curved member having a first internal/external curvature in its length direction orthogonal to the width direction of the main portion and a second internal/external curvature in its width direction orthogonal to the length direction of the main portion, wherein the first and second internal curvatures are configured to form collectively an internal surface adapted for conforming with an outer profile of a wearable device to facilitate proper mounting of the clasp device over the wearable device;
• and the first and second external curvatures are configured to form collectively an external surface adapted for facilitating a proper mounting of the clasp device over the wearable device.
