A lockable anti-fall catch connector includes a catch member, a locking shaft, and a locker unit. The catch member includes a retention arm and two sleeve members provided at two ends of the retention arm, wherein a first locking portion is provided at one of the sleeve members. The locking shaft is slidably extended between the sleeve members, wherein the locking shaft has a second locking portion detachably coupled with the first locking portion to lock up the locking shaft at the retention arm. The locker unit includes a locking element slidably coupled at one of the sleeve members to engage with the locking shaft, wherein after said locking element is disengaged with the locking shaft, the locking shaft is actuated to disengage the second locking portion with the first locking portion in order to slide the locking shaft with respect to the catch member.

A self-locking device for a mountaineer or a speleologist climbing up a rope is provided herein. The device includes a main body having an inner face with a sliding seat for the rope. The sliding seat is partially defined by a part of the body of the device folded upon itself and partially defined at a bottom and laterally by the inner face of the body of the device. The device includes a cam member associated with the body and able to tilt around an axis X from an open position to a position holding the rope. The self-locking device also includes one or more pulleys associated with the body. The one or more pulleys are arranged so that a longitudinal axis Z lies on a plane parallel to a plane a of major extension of the body and perpendicular to a sliding direction of the rope.

An anchoring and support climbing device may include a central body suitable for being connected at one end to a wire, and at least one cam rotatably arranged with respect to said body by means of a rotation pin which can be positioned or dislocated with respect to said body between a minimum overall dimensions position and a maximum overall dimensions position of said rotation pin, by movement means, and by and locking means of the same rotation pin. The movement means may include at least two rockers opposed to each other. The locking means may also include a ratchet locking mechanism suitable for allowing single direction rotation with respect to the second rotation pin, so as to prevent the rotational movement of the rockers.

A simple hand held tool for removing climbing protection, with said tool's body comprising at least two sub-assemblies connected by a joint, rendering the tool able to modulate in size (by collapsing, folding, retracting, extending etc.). Size modulation additionally provides coverage or protection of the tool's hooked tip. This manually operated tool increases a user's safety and freedom of movement by modulating tool size, and preventing the nut tool hook or shaft from being a hazard or interfering with the user's activities, yet preserving normal nut tool function when in a deployed mode.

A climbing instrument that comprises a first ring, a second ring that is larger than and engaged with the first ring. The second ring may comprise a gate that traverses a portion of the second ring and a rotatable cylinder that is positioned opposite the first ring and integrated within the second ring. The climbing instrument may also comprise a plurality of curved protrusions connected to and extending out and away from at least one of the first ring and the second ring.

A convertible backpack that can be used as an edge protection mat to protect ropes against abrasion and includes a flexible mat or sheet that can be configured into a pack and carried on the back of a user to carry equipment, clothing, or other gear. A pair of rope protection members are affixed to the outer surface of the sheet for carrying the pack and are easily removable for use alone or in combination with the flexible sheet to further protect ropes.
