A securing device that requires wearer assistance for removal has a clasp that is unlocked by simultaneously disengaging movable ratchet teeth and sliding one half of the clasp past the other half. The clasp has a first portion and a second portion, each portion including a male connector having fixed ratchet teeth and a female connector having movable ratchet teeth. When the securing clasp is locked together by connecting the male connector of the first portion with the female connector of the second portion, and vice versa, it provides for the securement of an adjoining wristband. The securing device can be unlocked by anyone using a two-hand grip but not by a wearer of the device on their wrist, because the wearer only has the use of one hand to unlock the securing device.
