ABSTRACT:
A clamp is disclosed for use in deep sea oil exploration operations. The clamp includes a pre-formed metallic belt (12) to which a first rigid metallic curve (13) is welded. The rigid metallic curve reinforces and protects the anchorage housing of an electro-hydraulic hose which is secured by the clamp. The belt (12) further includes a second rigid metallic curve (14) to reinforce and protect an electric cable which is secured by the clamp. The belt includes rigid symmetrical forks (15) and (16) that are welded in the rotation area of screws that serve to tighten the clamp. The clamp includes a body made of vulcanized rubber having three tips (26), (27) and (28), which are formed at equidistant angles of 120°. The clamp body includes a larger bore hole in the center (17), a medium bore hole in half oblong form (9) in the tip (27), a small bore hole in half oblong form (8) in the tip (26), and a bore slot (18) in the tip (28) suitable for the opening and closing of the clamp (1). The clamp body further includes a small bore hole (10) located in one side of said slot (18), where two threaded casters (2) are set up having a smaller diameter than the hole (18) in order to make the caster (2) pivotable inside of the hole (18).
