Disclosed is a pipe coupling or a pipe clamp which has an outer clamp band with an outer longitudinal slot, an inner clamp band with an inner longitudinal slot and a tensioning mechanism arranged on the outer clamp band. The inner longitudinal slot is offset in relation to the outer longitudinal slot. A separate flat spanning element is provided on the inner clamp band in order to span the inner longitudinal slot. The spanning element extends from one side of the inner longitudinal slot towards the other side of said longitudinal slot.

A hose repair system including a first clamping member and a second clamping member, each clamping member including an interior surface with a concave curve along the width and a pair of longitudinal grooves formed at the intersection of the first and second clamping members. Each longitudinal groove extends from end to end of each clamping member. The system also includes at least one fastener for clamping the first and second clamping members together.

A clamp for repair of a pipe coupling, includes a clamp unit including a side wall with an inner surface, the inner surface having a curvature dimensioned to match an outer curvature of a pipe coupling to be repaired. A coupling on the clamp unit is constructed and arranged to couple a first portion of the clamp unit with a second portion of the clamp unit. The coupling, when secured, operates to induce a radially inward force on the inner surface of the clamp unit. A window is formed as an opening in the side wall of the clamp unit. The window is dimensioned to expose a flange of a pipe coupling to be repaired.

A coupling assembly having first and second sleeves configured to be tightened to a fluid conduit, a radial-split gasket configured to be positioned between the sleeves and the fluid conduit and having an outer gasket layer and a separate inner gasket layer configured to be selectively disengaged from each other, an inner circumferential surface of the outer gasket layer and/or an outer circumferential surface of the inner gasket layer comprising a plurality of circumferentially spaced retaining protrusions interfacing between the inner and outer gasket layers, each of the retaining protrusions having a separation portion and an engagement portion connected to the other gasket layer by a gasket layer connection such that the engagement portion will separate at the separation portion under an applied separation force prior to the engagement portion separating at the gasket layer connection.
