1. A descent control device comprising a housing, wherein the housing comprises
a rope entrance and a rope exit for a rope,
a channel between the rope entrance and the rope exit, the channel having at least one curvature of at least 270 degrees, for accommodating the rope internally in the housing,
an element arranged in the centre of the curvature, forming the inner radius of the channel, the element is non-concentrically rotatable between a free position and a stop position, the element is provided with an arm protruding out through the housing for controlling the rotating between free and stop position,
Wherein peripheral edge of the element comprises a first portion being curved closely corresponding to the curvature of the channel in the housing, and a second portion as a remaining peripheral edge of the element being less curved, wherein the remaining peripheral edge faces the curvature when the element is in a free position, and the remaining peripheral edge faces out of the curvature when the element is in a stop position, whereby the channel in the curvature is more narrow along its whole length when the element is in stop position than in free position,
wherein the housing further comprises limitation means arranged on the outside of the housing, limiting the minimum distance between an arm and the housing.
