ABSTRACT:
In a device for connecting and disconnecting hoses or pipes to and from difficultly accessible structures such as under water, it is aimed at providing a reliable device, which will be easy to operate, lends itself to repeated connecting and disconnecting of the hoses or pipes, also if necessary by remote control, and which is to a considerable extent selfcleaning. To this end the device has a movable supporting structure for carrying the hose or tube by engaging a freely rotatable end part thereon and an endless chain slung around a driving pinion and around two other chain pinions in the device, which latter pinions are positioned one to each side of the hose or pipe, are movable towards and away therefrom and are urged away therefrom. The chain is slung around part of the periphery of said part to engage a gear ring thereon with its run between the said two other chain pinions. The structure thereby is not sensitive to fouling and to strict dimensional tolerances as more resistance when rotating the end part of the hose or sleeve will bring the said two chain pinions closer thereto and will make the chain tend to engage deeper into the holes between the teeth of the gear ring on the hose or sleeve.
