In a tool for mounting and dismounting a pipe clamp provided by the present creation, a first end portion and a movable second end portion are separately disposed on a base, and a connecting rod mechanism is used to convert circular motion into linear motion of the second end portion by force, so as to reduce the distance between the second end portion and the first end portion, thereby achieving an effect that the annular inner diameter of a pipe clamp is increased when the pipe clamp is held between the first end portion and the second end portion.

A spring clamp marker assembly is composed of interconnecting spring clamp hose markers that provide a positive and easily changeable means for marking hoses used to maintain HVAC equipment and for any other suitable application. The interconnecting spring clamp hose markers may also be used with power cables or other linear items with a generally circular cross section.

A tube coupling comprising having a coupling body with an opened ended throughway to receive a tube. A collet is located in the open end of the through way having a ring and flexible arms extending generally axially of the ring into the throughway. The throughway has a tapered surface convergent towards the open end and the collet arms have heads at their distal ends for engaging the tapered surface and a tube extending through the collet into the throughway to be compressed against the tube by the tapered surface with outward movement of the collet with respect of the throughway to secure the tube in the throughway. A collet lock is formed on the collet, and the collet has a locked rotary position Either the body or the collet has a cam surface and the other has a cam follower.

A collet located in the open end of the through way has a ring and flexible arms extending generally axially of the ring into the throughway. The throughway has a tapered surface convergent towards the open end and the collet arms have heads at their distal ends for engaging both of the tapered surface and a tube extending through the collet. A collet lock is formed on the collet, the collet having a locked rotary position and an unlocked rotary position. One of the body and the collet is provided with a cam surface and the other is provided with a cam follower, the cam surface being provided to provide the locked and unlocked positions. The disclosure also extends to the collet.

There is provided a hose clamp. A clamp has a clamp body. On one end portion of the clamp body, a slit is provided and a first grip piece is formed. On the other end portion of the clamp body, a second grip piece is formed. A holder is provided with a holding groove and a grip portion. The holding groove has an insertion opening opened in a direction intersecting with an axial direction of the clamp body, and a side opening opened on at least one end side in the axial direction of the clamp body. A protrusion is provided on at least one of opposing inner surfaces of the holding groove. When the pair of grip pieces are inserted in the holding groove, the protrusion can be arranged inside a part of the slit located in the first grip piece.

A spring clamp retainer includes a first end configured for retaining a spring clamp in an unclamped state until removed, a second end configured for grasping with at least one finger. An intermediate portion extends between the first and second end that includes a top and bottom surface wherein the top surface is configured for resting a thumb and holding in the palm of a hand, and the bottom surface is configured for grasping with at least one other finger.
