halves, said halves meeting at an interface and being
controllably separable, said device comprising:
a single fastener for coupling said two halves one to the
other to form said clamshell;
a plurality of engaging elements, said engaging elements
being positioned at said interface along at least a portion of
each clamshell side and each comprising an item from the set
consisting of:
(i) a tooth added to one of said halves and a matching
recess added to the other of said halves,
(ii) a snap added to one of said halves which engages a
receptacle added to the other of said halves,
(iii) a post added to one of said halves and matching
receptacle added to the other of said halves, and
(iv) a pimple projecting from a surface of one of said
halves which engages a gasket contained in a recess in the other
of said halves;
wherein said engaging elements are oriented so that when
