  • Legs 161 of the eyelet 16 are provided with bores 20 in circular bush portions 16b.
  • the eyelet 16 is attached to the body 12 using a pin 22, typically manufactured to EN24 standard, which passes through the bore 20, and an expandable sleeve 24 located in bore 14 of the body 12, sleeve 24 typically being formed from spring steel.
  • Sleeve 24 typically expands when the pin 22 passes through it, wherein it contacts bore 20 of the body more rigidly.
  • sleeve 24 prevents the pin 22 from rotational movement, but allows the bushes 16b (and hence the eyelet 16) to pivot on pin 22 relative to the body 12.
  • the pivotal movement of the eyelet 16 in relation to the body 12 allows the connector 10 to flex when it is attached to a fishing sweep (not shown) , particularly when the sweep is being reeled onto a drum on board a fishing vessel.

  • Slug 26 also has a tapered point 30 which facilitates insertion of the slug 26 into the central nylon core of the sweep.
  • the outer strands of the sweep are preferably unwound from around the core and these strands engage with the recesses 28 when the body 12 is crimped to enhance the grip between the end of the sweep and the body 12.

  • the end 50e farthest away from the connector 10 ie the portion of sweep 50 which remains intact
  • Slug 26 is then inserted into bore 12r and is driven into the core 52 of the sweep 50, typically using a hammer. If necessary, a punch can be used to preferably drive the slug 26 to the position shown in Fig. 13, which is in the region of 15mm from the end of the sweep 50.
  • the recesses 28 of the slug 26 typically engage with the loose strands of the sweep 50.
  • the body 12 of the connector 10 is then crimped in the conventional manner (using an appropriate crimp pressure, typically in the order of 270 tons, and appropriate dies) to facilitate a strong and robust connection of the connector 10 to the sweep 50.

  • the body 12 of the connector is crimped onto the end 50e of the sweep 50 which is intact (ie is not stripped) and thus makes a more robust and reliable connection.
  • This is particularly advantageous as the weak point of the conventional crimping methods is usually at the neck (ie the junction between the portion of the sweep with the strands unwound and the portion with the strands intact) of the connector 10.
  • the body 12 crimped directly onto the sweep 50 as opposed to be crimped onto the core 52 surrounded by strands (not shown) , a stronger connection is made, particularly at the neck.
  • the aluminium crimp ring is then positioned approximately 5mm from the face of the body 12 and is crimped to prevent the strands from fraying back.
  • the eyelet 16 is attached to the body 12 using the method described above, once the sweep 50 has been crimped into the body 12. That is, the spring sleeve 24 is inserted into bore 14. The eyelet 16 is then attached by inserting the pin 22 through the bushes 16b and the sleeve 24, the connector 10 typically being placed on a solid object and the pin 22 being driven in using, for example, a hammer until both ends of the pin 22 are flush (as shown in Fig. 13) .
  • a net can then be attached to the eyelet 16 in any conventional manner. It will be appreciated that any connection may be made to the eyelet 16, such as a crane hook or the like, and connector 10 should not be limited to the use described herein.
  • This method of attaching the sweep 50 to the connector 10 allows the nylon combination wire from which sweeps are typically made of, to be crimped to a connector, the crimping being able to withstand loads of around 15 tonnes or more.
  • Connector 100 is similar to connector 10, except that a swivel is used to give rotational movement to the eyelet 116 as opposed to pivotal movement only.
  • the swivel also allows the eyelet 116 to rotate. This is advantageous, as the sweep often becomes twisted along its longitudinal axis in use.
