Belaying and rappel device (1) for controlling the unwinding of a rope, comprising: a tubular rigid body (2) which extends along a longitudinal axis (A-A) between a rope introduction end (3) and a rope retention end (4), the body (2) having at least one through-tunnel (5) which has an oblong cross section which extends along an extension axis (B-B) for the passage of a half-loop of the rope between the rope introduction end (3) and the rope retention end (4), the through-tunnel (5) being limited by two opposing lateral body walls (6, 7) and by two opposing front body walls (8, 9), a retention bow (10) which is fixedly joined to the body (2) and which extends the body (2) beyond the rope retention end (4) in order to allow the passage and the retention of a fitted carabiner-type hook which extends through said rope half-loop, at least one of the opposing lateral body walls (6, 7) being provided with a blocking aperture (11, 12) which extends from the rope introduction end (3) and which is shaped for the lateral passage of one of the strands of the rope half-loop in order to ensure its selective blocking. |
