Mounting device for an elongate flexible member

1. A mounting device for an elongate flexible member extending through an aperture, comprising:

an elongate body having a longitudinal axis;

an internal passageway passing through the elongate body parallel to the longitudinal axis, for receipt of the elongate flexible member;

a plurality of apertures in the elongate body; an engagement member in each aperture and constrained to move along a displacement axis inclined to the longitudinal axis of the elongate body;

a plurality of actuation members,

each engaged with a respective engagement member, whereby displacement of the actuation member in a first direction displaces the engagement members outwardly to project beyond the periphery of the elongate body and displacement of the actuations members in a second, opposite direction displaces the engagement members inwardly; and

biasing means biasing the actuation members in the first direction.

2. The device as claimed in claim 1 , comprising a plurality of elongate passages in each of which one of the actuation members is located.

3. The device as claimed in claim 2 , wherein the elongate passages are located parallel to the longitudinal axis of the elongate body.

4. The device as claimed in claim 1 , wherein the internal passageway is cylindrical.

5. The device as claimed in claim 1 , wherein the outer peripheral face of the elongate body is cylindrical.

6. The device as claimed in claim 1 , wherein the plurality of apertures are spaced around the elongate body at a first longitudinal position of the elongate body.

7. The device as claimed in claim 6 , comprising a plurality of recesses spaced around the elongate body at a second longitudinal position of the elongate body.

8. The device as claimed in claim 7 , wherein the plurality of apertures correspond circumferentially with respect to the plurality of recesses.

9. The device as claimed in claim 8 , further comprising a plurality of elongate passages in each of which one of the actuation members is located wherein the elongate passages in which the actuation members are located extend between each aperture and corresponding recess.

10. The device as claimed in claim 1 , comprising a moveable tubular sleeve member on the exterior of the elongate body.

11. The device as claimed in claim 7 , wherein the moveable tubular sleeve member conceals the plurality of recesses.

12. The device as claimed in claim 10 , wherein the movable tubular sleeve member is secured to the actuation members.

13. The device as claimed in claim 1 , wherein the engagement member is constrained to move in the radial direction relative to the longitudinal axis.

14. The device as claimed in claim 1 , wherein the engagement member is a locking dog.

15. The device as claimed in claim 1 , wherein the biasing means is a spring.

16. The device as claimed in claim 1 , comprising connecting means for connection to an elongate hollow protective device for passage of the elongate flexible member.

17. The device as claimed in claim 16 , comprising connecting means at both ends of the elongate body, each connection to an elongate hollow protective device.

18. The device as claimed in claim 16 , comprising connecting means for connection to a centraliser.

19. The device as claimed in claim 14 , comprising connecting means for connection to a cable protection device.

20. The device as claimed in claim 14 , comprising connecting means for connection to a bend stiffener.
