Abstract: A restraint device, in particular for training purposes, having a holder which is or can be anchored in a fixed position and from which a rope that can be attached to a user can be drawn out against a restoring force via a movement path of the user. Apparatuses for generating the restoring force by sliding friction are provided and include a roller that can be rotated by winding the extendable rope around the roller and a brake device inhibiting the rotation of the roller.
