No ugly and inefficient loop is required:
>> C = {'Tcgh','A6','1214'};
>> out = sprintf('-%s',C{:});
>> out(2:end)
ans =
Tcgh-A6-1214

Many Thanks @Stephen Cobeldick but i'm trying to avoid cellfun and prefer to use for loop for future use.

res = strCell{1};
for k=2:length(strCell),
res=[res '-' strCell{k}];
end;
disp(res);

This expands the output res on each iteration, which is not efficient:
See my answer for a simpler and more efficient solution that does not use a loop.
