We report on a search for the process $B^{+} \rightarrow
\kern 0.20em\overline{\kern -0.20em K}{}^{*0}(892) K^{+}$
using $232 \times 10^{6}$ $\Upsilon(4S) \rightarrow B
\kern 0.18em\overline{\kern -0.18em B}{}$ decays collected
with the \mbox{\slshape B\kern-0.1em{\small A}\kern-0.1em
B\kern-0.1em{\small A\kern-0.20em R}} detector at the
PEP-II asymmetric-energy $B$ Factory at SLAC.
From a signal yield of $25 \pm 13\,[stat]\,\pm 7\,[syst]$
$B^{+} \rightarrow \kern 0.20em\overline{\kern -0.20em K}{}^{*0}(892)
(\rightarrow K^{-} \pi^{+}) K^{+}$ events,
we place an upper limit on the branching fraction
${\cal B}(B^{+} \rightarrow
\kern 0.20em\overline{\kern -0.20em K}{}^{*0}(892) K^{+})$
of $1.1 \times 10^{-6}$, at the $90 \%$ confidence level.
