"'Colloportus!' gasped Hermione and the door sealed itself with an odd squelching noise."
Hermione Granger[src]

The Locking Spell (Colloportus) was a charm that locked doors, making it so that they couldnot be opened manually. This charm was featured in The Standard Book of Spells, Grade 1[2] and its counter-charm was the Unlocking Charm (Alohomora).


The Locking Spell would shut and lock a door, preventing manual entry. The door could be unlocked with the use of a key or unlocking spell.


This charm was taught to first year Charms class students at Hogwarts School of Witchcraft and Wizardry during the 1984–1985 school year by Professor Filius Flitwick.[3]

—Harry Potter on the spell used on the doors[src]


Colloportus is composed of the prefix "collo—" deriving from Latin colligo meaning to bind together or possibly Greek κολλάω, κολλώ (collo) which means "to glue, stick" and Latin portus meaning door.
