The TE Connectivity 1-794616-0 is the 10-position, dual-row plug housing from the Micro MATE-N-LOK series.
The crimp terminals used are the Micro MATE-N-LOK male pin contacts — these are ordered separately under a different TE part number (the specific terminal depends on the wire gauge, typically 20-24 AWG for this series). The housing accepts the terminals before insertion, and the terminal position assurance (TPA) feature in the receptacle side (if used) confirms full seating. No secondary locking device is built into this plug housing itself.
