• a first strap end having a wide strap section and a connecting narrow strap section terminating in a free end of said first strap end, said first strap end defining a plurality of longitudinally spaced holes along the center of said wide strap section;
• a second strap end having a second strap section terminating in an integral substantially rectangular buckle frame defining a substantially rectangular frame opening therein and having first and second spaced transverse cross members, said frame opening having a wider transverse dimension than said wide strap section, said buckle frame incorporating an overmolded rigid frame insert of hard plastic material and further defining at least one short rigid tang arranged at the center of said first transverse cross member to cooperate with and enter a selected one of said holes for selectively adjusting the position of said wide strap section in said frame opening, said second strap section defining a transverse slot therethrough longitudinally spaced from said buckle frame, said slot having a wider transverse dimension than said narrow strap section, said slot further having end walls which are offset inwardly and outwardly from one another, wherein sloping guide walls are provided to receive and guide the narrow strap section, whereby said narrow strap section may be inserted through said transverse slot to serve as a keeper to retain the free end of said narrow strap section between said second strap section and said wrist of a wearer and to prevent disengagement of said short rigid tang from said selected hole.
