Abstract
The invention relates to installation of underwater equipment, more specifically for use in oil-fields. This new device for connecting and disconnecting a guide line between an installation on the seabed and a floating platform comprises a cylindrical adapter, free to rotate on its own axis, and provided with means of guiding, directing, positioning lengthwise and locking into a cylindrical sleeve, forming the upper portion of a guide post fixed to the underwater installation. The locking mechanism comprises at least one locking head, which extends out from and can be detached from a locking bar. The lower edge of this locking head forms a retracting cam, while the horizontal upper surface forms a locking edge. Such a device can be used to connect and disconnect the guide line by remote control, from a floating platform.
