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

The Locking Spell[2] (Colloportus) was a charm that locked doors, making it so that they could not be opened manually.[1] This charm was featured in The Standard Book of Spells, Grade 1[2] and its counter-charm was the Unlocking Charm (Alohomora).


This charm was used to lock mechanisms

During the 1987–1988 school year at at Hogwarts School of Witchcraft and Wizardry, Professor Filius Flitwick taught his fourth-years how to cast this particular charm in Charms class.[3]


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.

Behind the scenes

"It appears to be some sort of locking charm"
— 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.
