Abstract: A pulley includes a securing head and a first flange. A first shaft extends from the first flange. A sheave is mounted rotatable around the first shaft in one direction of rotation only. A cam is mounted able to move away from or towards the sheave. A spring is fitted to exert a force moving the cam towards the sheave. A handle is mounted on the first flange to move the cam between the first and second positions.

Abstract: A rescue device includes a pulley includes a support flange with two rotation shafts mounted salient and extending in a first direction. Two sheaves are mounted rotatable around two rotation shafts to define a running line of a cable. Two flanges are mounted rotatable between a first position and a second position. A first blocker is configured to present a first position blocking the first flange in the closed position and a second position allowing rotation of the first flange. A second blocker is configured to present a first position blocking the second flange in the closed position and a second position allowing rotation of the second flange. The second blocker is independent from the first blocker.

Abstract: The quick link has a body defining an open link with two opposite ends. The body comprises a straight portion separating two curved portions. A locking ring is fitted rotating and sliding with respect to the body with a closed position closing the link and an open position where the quick link is open. A shutter is fitted removable with respect to the body. The shutter defines an attachment means fixing the shutter to the straight portion and a blocking system fixing the shutter to the locking ring. The attachment means and blocking system are formed by a ring or a hook. The attachment means and blocking system allow rotation of the shutter with respect to the body when the locking ring is in the open position and prevent rotation of the shutter when the locking ring is in the closed position.
