Abstract: The connection device (1) comprises a coupling connector (5) in the form of an open ring (5a) with a closure finger (5b), which is rendered permanently integral, by means of an articulated connection or by means of a rigid connection, with a connection apparatus (4) which can ensure the selective connection to a rope (3). The manipulation of the connection device is thus facilitated, and the risks of incorrect relative positioning of the coupling connector (5) and the connection apparatus (4) are avoided.

Abstract: The self-blocking descender-belay device (1) according to the invention comprises: a first lateral guide flange (6) for the rope, comprising a braking nose (4e), a second lateral guide flange (7) for the rope, which is separated from the first flange (6) by a transverse gap (8) for passage of the rope, and can be displaced between a spaced position for putting into place and removal of a rope, and a closed position in which the rope is trapped in the transverse gap (8) for passage of the rope, a cam (4d) which is engaged between the first and second flanges (6, 7) and is mobile towards and away from the braking nose (4e), and is thrust towards the braking nose (4e) by a cam return spring, the transverse gap (8) for passage of the rope extending between a rope input in the vicinity of the braking nose (4e), and a rope output opposite, the rope output having a large opening such as to permit free orientation of the rope output end between a blocking orientation in which the rope surrounds the cam (4d), and a
