Preferably, the tongue (26) is formed as an extension of a lateral marginal portion (24) of the band-forming material which is folded over the adjacent main portion (11) thereof, and the recess (30) being defined between the folded-over marginal portion (24) and the adjacent portion (11) at the opposite end (12) of the band. Preferably also end portions (16, 17) of the band are folded inwardly at the joint (35).</p> |
