A connector comprising a cylindrical sleeve device having a first part (210), with an external screwthread on its outer side, and a second part (224), with an internal screwthread on its inner side. One of the screwthreads engages a corresponding screwthread on a further part (42) when the device is in use. At least a portion of the said second part (224) is yieldable. A locking part (240) is provided with a screwthread which engages the other of the screwthreads of the cylindrical sleeve device when the connector is in use. The said second part (224) and the locking part (240) have mutually engageable portions which, when the locking part (240) is tightened relative to the cylindrical sleeve device, interengage to cause yielding of the second part (224) or yieldable portion thereof. This effects locking of the cylindrical sleeve device with respect to such a further part when the connector is in use. |
