Crazy question

[ocean5ail5]

Ok know you used to get something "no idea what it was called.
Was like a tube and then you if you put like fingers in either side and try to pull it out it only grips harder.
Were thinking if there is maybe something like this that can be used on end of halyard and another rope so you could quickly pull halyard out for cleaning while inserting a line to pull it through. Then when done to put halyard back or how do you Sailors do it quick and easy.

You’re referring to what’s commonly called a “finger trap”. It could work, and in fact one company uses such a technique for rope clutches.
If you want to use it to join ropes to pull a halyard or other rope through a confined channel you’ll need to tape the leading edge of the trap to assure it isn’t pushed back when it encounters a snag, which would cause the grip to open up. The trailing rope section being pulled must also be under continuous tension or the grip would be lost.
Overall, it it depends on too many factors to be reliable and secure. Probably just better to stitch and tape, and forget about this use for the idea.

This is why all halyards should have a reeving eye splice at the bitter end, it allows for a secure and easy attachment.

There are numerous ways to attach two lines end to end. The most secure is to sew the ends together and wrap lightly with tape to ensure it will feed over a sheave without binding.
The implement you described is known by several names, such as a Chinese finger trap or a Chinese finger puzzle.

Cheaper to buy waxed thread, sew 🧵 end to end and never wonder why the Chinese finger trap failed at the turn of the sheave

Sew it. Great simple advice in the above post ...but..What in heavens name is that blue thing with its mouth open ?
No wonder nature gave children lungs to scream.
What is it? Carlosproa.

Thank you Sailors.

The Reeving/Flemish eye will probably be safest and most cost effective way for me, because will probably put halyards away quite often. Main mooring area have a wind that blows find sand dust quite often and would extend halyards life probably quite a bit by doing this.

Chinese handcuffs!

As I recall, they weren't particularly effective.

Agree that the way to join two lines for this purpose is to sew them. In addition to the basic tools I have onboard, I have a small sewing kit with sail thread, some big needles, and a sewer's palm. Takes minimal skill and just a couple minutes to sew them together. Makes a remarkably strong bond.

Electrical supply houses sell such a tool: https://www.lowes.com/pd/Southwire-W...00-lb/50114297

Thin mouse line a double sheet bend and gaffa tape over it never failed me...

If you sewed the finger trap onto the line that would work, but then you might as well just sew and tape. No need for the trap.
