## Abstract

A safety apparatus on a rope, including a first flange-plate, an operable second flange-plate, and a mechanical indicator collaborating when the swivelling movement takes place with both the first pivot-pin and a latch to indicate that the second flange-plate is in the closed and latched position, or in an unlatched ready-to-open state.

## Claims

### Claim at position 1

1-8. (canceled)

### Claim 9

A safety apparatus on a rope, comprising:
a first flange-plate and a movable second flange-plate delineating a transverse space in which a roller is arranged fitted on a first pivot-pin integral to the first flange-plate,
articulation means of the second flange-plate allowing a swivelling movement between a closed position clamping the rope in captive manner in the transverse space, and an open position for fitting the rope on the roller,
and latching means of the second flange-plate in the closed position, said latching means comprising a pivoting latch controlled by control means,
wherein the latch is associated with a mechanical indicator integral to the second flange-plate, said indicator collaborating both with the first pivot-pin of the roller and with the latch to indicate that the second flange-plate is in a latched closed state or in an unlatched ready-to-open state.

### Claim 10 (depends on 9)

The safety apparatus according to claim 9, wherein the indicator is formed by an indicating lever articulated around a pivot-pin integral to the pivoting latch, said indicator being in a visible state through a hole of the front face if the latch is actuated in the unlatching direction or if the second flange-plate is not properly closed.

### Claim 11 (depends on 9)

The safety apparatus according to claim 9, wherein the indicator is located on the pivoting latch, and an anti-return feeler element collaborates with said latch both to keep the latter open and to keep the indicator visible if the movable second flange-plate is not correctly closed on the first pivot-pin.

### Claim 12 (depends on 11)

The safety apparatus according to claim 11, wherein the latch with its indicator constitutes a bistable lever in both the latched and unlatched positions.

### Claim 13 (depends on 9)

The safety apparatus according to claim 9, wherein the roller is in the form of a rotary pulley mounted idle on the first pivot-pin.

### Claim 14 (depends on 13)

The safety apparatus according to claim 13, wherein the roller is associated with a blocking trigger designed to block the rope against the roller.

### Claim 15 (depends on 9)

The safety apparatus according to claim 9, wherein the second flange-plate comprises a hollow second pivot-pin housed in an opening of the first flange-plate to constitute said articulation means, the external diameter of the hollow second pivot-pin being smaller than that of the opening to define a translational clearance of the first flange-plate in the heightwise direction.

### Claim 16 (depends on 9)

The safety apparatus according to claim 9, wherein the second flange-plate comprises a securing notch in which the head of the first pivot-pin engages following movement of the second flange-plate to the closed position, and the latch is biased to the latched position by a bias spring.
