A clasp is configured to permanently interlock around a flexible strip of material and includes first and second interlocking members. At least one interlocking member includes a Bluetooth communication device. Each interlocking member can include a plurality of hooks and a corresponding plurality of recesses, where the recesses of one interlocking member receive the hooks of the other interlocking member to secure a band within the clasp between the interlocking members. The recesses can be completely internal to the clasp to prevent external tampering. Each of the interlocking members can include various protrusions and ribs that compress and secure the band within the clasp, so as to prevent movement of the band between the interlocking members when interlocked.

The present invention discloses an integrated buckle of metal and plastics, comprising a female buckle and a male buckle. The male buckle comprises a male buckle body and left and right pins connected to the male buckle body. The male buckle body is made of metal, the left and right pins are connected to the male buckle body by rotating shafts to form a side-to-side rotational structure. A plastic flick piece is located between two pins, the plastic flick piece is fixed to the male buckle body. An elastic arm is located on both sides of plastic flick piece respectively, the two elastic arms hold two pins respectively. The present invention uses metal material to make male buckle body and pins, and the elasticity of pins is derived from the elastic arms on both sides of plastic flick piece.
