The present invention relates to a device for connecting and separating masonry units, preferably bricks, which comprises a tubular body that fits the tubular shape of holes in the bricks. The device for connecting and separating comprises a portion that has a straight cross-section larger than the cross-section of the tubular body and disposed approximately midway along the length of the connector device, for separating the bricks that said device connects. The device also comprises at least one depression or channel along the entire length of the tubular body, the depression or channel acting as a spring. The connector allows walls to be assembled using only bricks and connectors so as to apply mortar ex post.

Disclosed is a fixing (1) for securing an article (21) to a surface (19). The fixing comprising a coupling arrangement (3) for coupling the fixing to an article such as cabling. Elongate members (5) extend from the coupling arrangement and are moved together to insert the fixing into a cavity (17), and spring apart to retain the fixing in the cavity. The elongate members have resiliently deformable inner formations (9). The inner formations engage with one another and resiliently deform when the elongate members are brought together, thereby increasing the pull resistance of the fixing. The inner formations are inwardly extending branches each presenting a ramped surface oriented towards the distal ends (8) of the respective elongate member, assisting in coupling an article to the fixing.

In order to provide an anchor element for fastening an article to a further article, this anchor element being simple and inexpensive to produce and enabling an article to be fastened to a further article simply and reliably, it is proposed that the anchor element should include a base body that takes a hollow form, at least in certain regions, and surrounds a receiving space for receiving a fastening element, wherein the base body includes one or more elastically yielding spring elements that are formed by one or more wall portions of the base body, and these project into the receiving space in an installed condition of the anchor element.

A sealing plug has an elastic sleeve of thimble-like basic shape. A wound-up band of the sealing plug is inserted in the sleeve. The number of windings or turns of the band can be reduced by rotating the inner end of the band, wherein the outside diameter of the band, and hence the outside diameter of the elastic sleeve, widens. The band can be inserted in pretensioned state into the sleeve and can slacken after insertion into an anchor hole. The band can be expanded in the anchor hole beyond the slackened state of the band. The sealing plug further has a latching mechanism, which prevents back-rotation of the expanded sleeve. The sealing plug enables a radial expansion, and hence a sealing of anchor holes of different diameter, without shortening of the axial sealing surface of the sleeve.

A fixing device for attaching a fastener to a wall, the device comprising a body having a fastener receiving aperture defined therein; and at least two arms pivotably mounted to the body between: a retracted position in which the device is insertable into an opening in a wall from a first side of the wall; and, an extended position in which the arms bear against a second side of the wall to inhibit removal of the device from the opening; in which the arms are configured to be retained in the extended position by a fastener inserted in the fastener-receiving aperture.

A support sleeve and an arrangement for supporting spaced-apart components or component portions, wherein the support sleeve is of one-part form and comprises a shaft having a first shaft portion, a second shaft portion adjoining the first shaft portion in an axial direction, and a third shaft portion adjoining the second shaft portion in the axial direction, wherein the first shaft portion and the third shaft portion form opposite ends of the support sleeve, wherein the second shaft portion comprises a retaining means that protrudes radially outward in relation to the first shaft portion and the third shaft portion and can be deformed radially inward counter to a restoring force, and wherein the shaft comprises a slot over the entire axial length of the shaft.
