  We relate all $C$-- and $P$--invariant anomalous triple vector--boson
couplings to the oblique electroweak parameters. LEP constraints on the latter
then yield the strongest and most general simultaneous bounds to date on the
former. Even if the oblique parameters assume their Standard Model values
precisely, these bounds would not shrink to zero---thus underscoring the need
for direct experimental probes at future colliders.
