The present disclosure relates to a pipe holding clip that defines a widthwise direction, a heightwise direction, and a lengthwise direction. The pipe holding clip can include a base portion, a pair of oppositely-arranged lateral portions extending upward from the base portion, a pair of holding arms extending inward from the pair of lateral portions and extending toward the base portion, and a support portion. Two sides of the support portion can be connected to the base portion or the pair of lateral portions. The support portion can include a working surface having an arc shape recessed toward the base portion. The pipe holding clip can provide a suitable holding force to limit the movement of a clamped pipe in an axial direction of the pipe.

A pipe clamp includes a linearly extending base portion. The base portion has a channel in which a pipe is positioned when inserted into the pipe clamp. The pipe clamp further includes two walled portions that extend from longitudinal edges of the base portion. The pipe clamp may further include a curved flexible support member that includes a fixed end and a moveable end. The fixed end is rigidly attached to an inner surface of one of the walled portions. Further, the flexible member is such that it extends in a curved manner, initially extending away from the inner surface of the walled portion and then curving inwards toward the walled portion into a recess.

A suspension aid 1 has a frame 3a, 3b and two curved arms 5, 7 rotatably connected thereto. The frame is provided with two pivot axes 9 about which the arms are rotatable. Between the arms there is a transmission element 11 which is slidable in the frame. A suspension element 13 to which an object can be suspended is attached to the transmission element. The arms are rotatably connected to the frame near a first end 5a, 7a and are provided with a toothing 17, 19. The transmission element is provided with two toothed racks 21, 23 which are in engagement with the toothings. The transmission element is provided with a contact surface 29 which, when the suspension aid is around the tube, comes into contact with the tube and stops the transmission element, whereby the frame moves with respect to the transmission element and thereby rotate the two arms with their free ends towards each other.

A coupling device for fluid lines includes a female part having an annular wall with an aperture, a locking arm with a cam, and a male part having an annular wall with an outside surface with a circumferential groove and defining a longitudinal channel extending into the groove. The male part can be inserted into and rotated within the female part. The locking arm has a cam, and can be rotated between a locked position in which the cam is in a locked position and an unlocked position in which the cam is in an unlocked position. When the cam is in either the locked or unlocked position, the cam engages the groove to retain the male part within the female part, unless the male part is rotationally positioned relative to the female part such that cam is aligned with the channel, in which case the male part is releasable from the female part.
