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.

First claim

1 . A clamp on a rope comprising:
a U-shaped body equipped with a trough for passage of the rope, an actuating lever having an aperture for attaching a safety means, and a cam for jamming the rope, said lever being housed in the trough by means of a removable pin, and a bias spring biasing the cam towards the rope.
wherein the spring is integrated in a housing of the lever of the cam by means of a securing cassette configured to place the spring in a pre-stressed state, said cassette been provided with clip-fastening means designed to be accommodated in the housing of the lever.

2 . The clamp according to claim 1 , wherein the cassette comprises an aperture for passage of the pivot-pin.

3 . The clamp according to claim 1 , wherein the cassette comprises an end-part for receiving the spring and flexible fingers coaxially surrounding the end-part for clip-fastening in the housing.

4 . The clamp according to claim 3 , wherein the spring is formed by a torsion spring of spiral-wound type fitted around the end-part of the cassette.

5 . The clamp according to claim 1 , wherein the cassette is configured to collaborate with a stop of the lever to ensure securing thereof in a groove of the body.

6 . The clamp according to claim 1 , wherein the cassette is made from moulded plastic material.

7 . The clamp according to claim 1 , wherein the pivot-pin of the lever with cam is able to be disassembled by any fast mechanical fixing means.

8 . The clamp according to claim 5 , wherein, when the lever is inserted in the trough, the cassette engages in the groove of the body presenting a single possible assembly position.
