TL;DR
A direct burial splice is an underground-rated connection, a gel-filled tube, resin-poured kit, or heat-shrink assembly, that joins or repairs buried cable while sealing the conductors against decades of soil moisture. Ordinary wire nuts wrapped in tape fail underground within seasons, corroding into the flickering-light or dead-zone complaints common in aging landscape lighting.
What it means
A direct burial splice is an underground-rated connection, a gel-filled tube, resin-poured kit, or heat-shrink assembly, that joins or repairs buried cable while sealing the conductors against decades of soil moisture. Ordinary wire nuts wrapped in tape fail underground within seasons, corroding into the flickering-light or dead-zone complaints common in aging landscape lighting. Listed connectors carry a direct-burial marking; for line-voltage circuits the NEC permits splices in earth only with such listed means, and burial without a junction box is exactly what these are engineered for.
