A clamping arrangement includes a clamp member and an elastomeric member. The clamp member is operative in a first orientation having a first inner diameter and a second orientation having a second inner diameter. The first diameter is greater than the second diameter. The elastomeric retaining member is carried by the clamp member and is operative to temporarily retain the clamping arrangement to a first tubular member having an outer diameter less than the first inner diameter when the clamp member is in the first orientation.

A fastening device is useful for at least one supply hose and/or at least one supply line for fastening to an industrial-robot arm with a holder, an assignable holder unit for the supply hose and/or the supply line, and a lockable tensioning element. The holder is arranged on the lockable tensioning element so that the holder, by the tensioning element being clasped and locked around the industrial-robot arm, can be fastened and/or positioned flexibly on the industrial-robot arm and thus in the event of the holder being connected to the assignable holding unit the supply hose and/or the supply line can be oriented in a specific manner.

A reinforced hose includes an inner layer, a reinforcing intermediate layer, and an outer layer. The inner layer has and inwardly projecting sealing rib extending circumferentially on an inner surface thereof. The inner surface may also have an end stop to be engaged by a fitting received in the hose. The outer layer has a pair of annular clamp guides projecting outwardly which are axially spaced from an end of the hose. The sealing rib is positioned between the clamp guides to indicate an optimum location for a hose clamp.

An operator is enabled to easily identify the normal attachment direction of a ground clip and set the ground clip in a correct direction. Provided is a hose attachment structure in which a ground clip is attached over a grounded electroconductive pipe and a flexible hose inserted onto an outer face of the electroconductive pipe, wherein the ground clip includes a coil part that is attached to the outer face of the electroconductive pipe and an outer peripheral surface of the flexible hose and a pair of pinch parts that protrudes from both end parts in an axial direction of the coil part and faces each other, and one pinch part among the pair of pinch parts has an asymmetrically-shaped indicator part having directivity in the axial direction of the coil part.

Disclosed are methods and apparatus that allow hand forces to easily cinch up and tighten a slotted band of a hose clamp to a position where a worm gear screw may then be used to firmly tightening the hose clamp around a hose or pipe. A cinching operation may be accomplished using a pawl apparatus provided at one end of a hose clamp having a centrally located downwardly facing tooth provided between a pair of oppositely positioned side walls which act as guides for receiving a slotted band of a hose clamp. A tightening operation may then be accomplished by turning the screw of a worm gear at the other end of the hose clamp. The hose clamp may be removed by releasing the pawl assembly or unscrewing the worm and gear screw.

A securing tool and methods for its use are described herein. In various embodiments, the securing tool may include a handle and one or more prying members positioned at a first end of the securing tool opposite the handle. The prying member(s) may be shaped to engage a release of a self-tensioned hose clamp to cause the handle to be manipulable to spring the self-tensioned hose clamp. The securing tool may include first and second sensors configured to provide first and second signals, respectively, that are indicative of sensed occurrence of first and second events after the handle is manipulated to spring the self-tensioned hose clamp. In various embodiments, if the first and second signals satisfy a criterion, the hose clamp may be deemed to have been properly installed onto a hose or other conduit.

A device having a tension retaining clip for use with an annular belt or hose clamping device having radially extending ends. The retaining clip may be used, for example, for compressive emplacement of the annular belt or clamp used to secure a hose. The retaining clip may further include an extraction ring. The radially extending ends of the annular belt may each include first portions extending in radial directions from the belt, and second portions extending perpendicularly from the first portions. The retaining clip may receive and retain the second portions of the extending ends of the annular belt within a retaining cutout, which extends between a free end of the retaining portion and a retaining side surface proximal to the extraction ring. In the retained position, the annular belt may thereby have maximum expanded diameter, due to compression of the extending ends within the cutout relative to one another. The annular belt may be compressed to a smaller diameter by disengaging the tension retaining clip from the extending ends of the annular belt. The cutout may have a cutout surface that extends between the free end of the retaining cutout and the retaining side surface, such that two corners of the cutout are defined thereby. The spring clamp may be disengaged from the annular belt by pulling the extraction ring portion so as to leverably pivot the retaining clip via the retaining clip's extending free end, which may extend toward and contact the annular belt during levered pivoting.

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.
