Abstract: The belay device comprises: a body with an inlet for insertion of a strand of rope forming a loop, a shaft and clamping part mounted on the body, the shaft extending in a longitudinal direction, an attachment opening collaborating with a carabiner connecting the belay device with a harness, a cam with a first end mounted in rotation on the shaft along a path so as to move towards or away from the clamping part and to define a first clamping position of the rope and another position. The cam, body and clamping part define a running path of the rope. The rope strand passes between the cam and the clamping part. The first end defines a through opening formed by the attachment opening. The connecting part is fitted movable in rotation with respect to the body along the path.

Abstract: A removable anchoring device comprising a fixed first part with an expansion head, and a movable second control part having wedging half-rings and a gripping knob associated with a stop and a spring. The stop is arranged on the fixed first part and is movable with respect to the gripping knob by a relative translational movement to disable any release command in a predefined position. The gripping knob is thus able to occupy a first axial adjustment position offset from the stop to indicate the non-locked state enabling the release command, and is movable to a second axial adjustment position in engagement against the stop to indicate the locked state and to disable said release command.
