An assembly of a drill pipe and a connector () for connecting a hose () to a side-bore () of a the drill pipe (), the drill pipe () having a wall () enclosing a main bore (), and the side-bore () extending through the wall () from the main bore () to the exterior of the drill pipe (), the connector () comprising a hose connector body () which forms a first end of the connector () which is adapted to be connected to the hose (), and a drill pipe connector body () which forms a second end of the connector () which is connected to the drill pipe (), the connector () having an exterior surface and an interior surface which encloses a bore () extending from the first end of the connector () to a second end of the connector (), the drill pipe connector body () being provided with at least one bayonet connector formation () which extends from the exterior surface of the connector () generally radially outwardly relative to the bore (), the bayonet connector formation () extending over less than half of the circumference of the exterior surface of the drill pipe connector body (), wherein the drill pipe connector body () is also provided with means for ensuring a substantially fluid tight seal between the connector () and the surface of the drill pipe () enclosing the side-bore ().

Drill pipe connector

A drill pipe having a tubular body through which is provided a main bore, a side port provided in an exterior surface of the body, a side bore extending through the body from the main bore to the side port, and a valve member which is movable between a closed position in which fluid flow through the side bore is substantially prevented and an open position in which fluid flow through the side bore is permitted, wherein the movement of the valve member between the closed position and the open position comprises translational movement, and the valve member is located at least predominantly within the side bore.
