such as ceramics to have high strength and a smooth surface and includes a permanent
assembly structure allowing easy securing of fastening pins (140) through press-fitting
of the fastening pins while providing high fastening force. The watch strap includes
outer connecting pieces (110), each including a pair of pin grooves (111) formed at
one side thereof and a pair of insertion grooves (112) formed at a back side thereof
to communicate with the corresponding pin grooves, a central connecting piece (120)
having a pair of pin holes (121) penetrating the central connecting piece to correspond
to the pin grooves of the outer connecting pieces, connecting pins (130) each including
a fastening part (131a) having fastening holes (132a) formed at opposite ends of the
fastening part, and a fastening pin having a latching step (144) formed at one end
of the fastening pin. The fastening part of each of the connecting pins is inserted
into the pin groove of the outer connecting piece through the pin hole of the central
connecting piece, and the fastening pin is press-fitted into the fastening hole of
the connecting pin through the insertion groove of the outer connecting piece and
