Identification bracelet and clasp

A patient identification bracelet is composed of a flexible strap (11) and a clasp (12), the clasp being formed of thermoplastic material and having a base member (16) fixed to one end portion of the strap and a hinged cover member (17) projecting laterally from the strap when the clasp is open. Holding elements project from at least one of the opposable surfaces of the cover and base member for engaging and holding the opposite end portion of the strap when the clasp is closed, and a mating post (21) and socket (22) are provided for locking the clasp in its closed condition. The post and socket are constructed so that the clasp, if forced open, cannot be reclosed. A relatively weak portion of the strap, located between the end portion of the strap that is fixed to the clasp and the identification-receiving portion of the strap, and also located between the base and cover members when the clasp is closed, defines a break-away zone for the strap when pulling forces of predetermined magnitude are applied thereto.
