Abstract: A tandem pulley includes a support bracket having the shape of an inverted U. The support bracket defines a through hole. A pair of sheaves is arranged in line inside the support bracket. Each sheave is mounted rotating freely around a spindle fixed to the support bracket. A carabiner is fitted in the through hole. A connector is configured to connect the support bracket with the carabiner. The connector is configured in such a way as to allow rotation of the carabiner around an axis parallel to the spindles of the pair of sheaves. A spring is connected to the support bracket, the spring being arranged to exert a force on the carabiner biasing the latter to a rest position by rotation of the carabiner.

Abstract: A connection device comprises a connector forming a ring with an open position and a closed position. A handle is fixed to the connector and has two extensions receiving a user's hands. The handle defines a tube extending in a first direction and a through hole arranged to pass through the tube perpendicularly to the first direction. A first end of a wire member forms a loop fixed to the connector in the tube. The second end of the wire member is fixed to the user. The connector passes through the through hole and the loop to fix the handle and the wire member to the connector.

Abstract: The tandem pulley comprises a pair of sheaves mounted in line between first and second flanges. A gate is fitted rotating with respect to the first flange between closed and open positions. The gate comes into contact with the second flange in the closed position to close a housing. The clamp is movable in rotation on the gate between a locking position locking the gate in the closed position and an unlocking position. The clamp has a prong pressing on the first flange and the gate in the locking position. The clamp has an actuating area separated from the first flange by the gate. Rotation of the actuating area from the locking position to the unlocking position corresponds to a movement of the actuating area away from the second flange. Rotation of the actuating area results in pivoting of the prong.

Abstract: An attachment device to an anchor point comprises a wire-like element provided with two ends a first end of which has a first ring. A clamp has two ends a first end of which can be inserted in the first ring. The second clamp end presents a second cross-section larger than the first cross-section. The first clamp end defines a through hole receiving a rope supporting a user. The second end of the wire-like element is fixed to the clamp via a first attachment point between the through hole and the second clamp end. A cord has a first end fixed to the clamp via a second attachment point and a second end with a second ring.

Abstract: A connector includes a first ring with a blocker collaborating with a rod. The rod is movable between a first position where the first ring is closed and a second position where the first ring is open. The blocker is movable between a first position collaborating with the rod to keep the first ring closed and a second position allowing opening of the first ring. A second ring includes a probe. The probe is connected to the blocker. When the distance between the probe and the sliding area is greater than a threshold value, the probe prevents opening of the first ring by the blocker. When the distance between the probe and the sliding area is smaller than the threshold value, the probe allows opening of the first ring by the blocker.

Abstract: The invention relates to a clamp with a cam, and with a removable pivot-pin, wherein the bias spring is integrated in a housing of the cam by means of a securing cassette configured to position the spring in a pre-stressed state. The cassette is provided with clip-fastening means designed to be fitted in the housing of the lever.

Abstract: An ascender/descender appliance for ascending and descending on a rope, comprising a body having attachment means to be connected to the user's harness and a clamping device able to be released on load. The clamping device is arranged outside the body and comprises a chain of metal links constituted by a succession of friction elements articulated on one another by connecting rods to form a series of gaps for the rope to pass in zigzag manner. Means are associated with the top link to trigger clamping of the ascender device.
