Claim:
1. A self-blocking descender-belay device to control a pay-out of a rope, said self-blocking descender-belay device comprising: a first lateral guide flange for the rope, wherein said first lateral guide flange is integral with a braking nose, a second lateral guide flange for the rope, a path for passage of the rope, said path having an intermediate section, said path separating said second lateral guide flange from said first lateral guide flange, said second lateral guide flange is configured to move between a spaced position and a closed position, wherein the spaced position is configured to allow the rope to be removed and placed into the path, and wherein the closed position is configured to trap the rope within the path for passage of the rope, a cam which is engaged between the first and second lateral guide flanges for the rope, wherein the cam is configured to be mobile by moving towards and away from the braking nose, said cam being separated from said braking nose by the intermediate section, a cam maneuvering unit, which can be activated by a user in order to displace the cam away from the braking nose, a cam return spring, in order to thrust the cam towards the braking nose, said path for passage of the rope extending on both sides of the intermediate section of said path, between a path input and a path output, wherein said path input is in a vicinity of the braking nose, the path output comprising a blocking output portion which passes around the cam, wherein an output end of the rope can pass along said blocking output portion and thus thrust the cam towards the braking nose, at least one flange selected from the group consisting of the first and second flanges extending longitudinally from a connection end area to a proximal end area, wherein the braking nose, the cam and said path for passage of the rope are situated in said connection end area, and wherein means for coupling a user to the self-blocking descender-belay device is situated in said proximal end area, wherein: the path output extends laterally between the first and second flanges, from the blocking output portion to a release output portion, the release output portion is in a line with the path input and the intermediate section of path, the line configured to define a generally straight passage configured to allow the output end of the rope to pass directly, wherein the generally straight passage is configured to allow the rope to pass without thrusting the cam towards the braking nose, and the generally straight passage is configured to have the rope tend to thrust the cam away from the braking nose.
