Kiril Mitov's most favourite attachment. To quote him "I had a really great fun building this attachment and recording the videos for it".

It's an attachment with a Rubber band and a Flywheel and a Gear Wheel and a Worm Gear. So much knowledge in just one small attachment. The goal of the attachment is to be able to have an active attachment without actually having a motor. So you can place that attachment and it will do the work for you instead of using a motor to power it. 

Build with LEGO Mindstorms EV3 set. 

When placing the rubber bands check out the tutorials

A LEGO Mindstorms construction for taking loops. Uses the same principle as a carabiner.

Building instructions for the Pinless Rubber Band Attachment:

These are building instructions for one of the greatest LEGO Mindstorms attachments that we've built. Super simple and easy to follow and at the end, you have an attachment with a rubber band that controls a lever and that could lift objects from the field. It could lift them up. Also because it is with a rubber band you don't need a motor and you could use the motor for other attachments. 

Building instructions for the One Attachment. Built from LEGO Mindstorms EV3 parts and with an Ultrasonic sensor we've used this attachment to accomplish most of the missions at FIRST LEGO League 2013.

SIngle robot attachment, many points. 

This is an pinless robot attachment designed for taking loops. It's built with LEGO MINDSTORMS Robot Inventor parts and it demonstrates how to collect a loop while moving with the robot. The attachment is designed for Luly, small LEGO Education SPIKE Prime competition robot with 3D building instructions. There are other attachments that are designed for taking a loop and locking it so that it does not fall, but they are more complex. Search for 'Carabiner' at FLLCasts.com

Attachment for grabbing loops build from LEGO MINDSTORMS Robot Inventor 51515 set. We use this robot attachment to accomplish missions with loops at FIRST LEGO League. Well, we use the principle, that is what's important. Check out the attachment and the course to understand the principle of grabbing loops.
