gaps in plot of piecewise function

Hi,
I want to plot a piecewise function, but I don't want any gaps to appear 
at the junctures. An easy example is:

s[x_] := Piecewise[{{-Sqrt[2]/2*Sqrt[-x + 0.5] + 2, x < 0.5}, {2, x >= 
0.5}}];
Plot[s[x], {x, 0, 1}]

It should be clear, that the piecewise function defined above is 
continuous, even at x=0.5. So there should not be any gaps appearing in 
the plot, but they do. Maybe it's a feature of mathematica, but 
nevertheless I want to get rid of the gaps. Any suggestions on how to 
achieve that.


Thanks in advance.
