A connector is disclosed for use in forming a joint between a first surface and a second surface. The connector comprises a housing. The connector also comprises a tendon. A portion of the tendon can protrude from the housing through a seal. The seal is configured to sealably cover an open end of the housing such that the tendon can move through the seal and laterally sideways across the open end together with at least a portion of the seal. Also disclosed is a connector system for use in forming a joint, and a method of installing a connector to form a joint, between a first surface and a second surface. The connector system and method comprises and makes use of the housing and the tendon.

A fastening system for chemically fastening an anchor, the fastening system including a chemical anchor that is a ready-for-use two-component mortar system based on albuminous cement, and an anchor rod comprising an attachment region and an anchoring region. The anchor rod is insertable into a borehole and has a profiled section including a plurality of expansion sections disposed axially in a row which are conically shaped.

A mounting device for affixing to a hole or bore in a support structure to anchor a line to the mounting device and support structure including a base with a hole passing through the base, hub extending from the base back surface having a pair of flexible legs and engagement members on the outer surfaces of the legs, a stirrup having a line receiving opening attached to the base front surface, and a locking member with a hook member at its proximal end and a distally extending shaft dimensioned to pass through the hole in the base and enter the distally extending cavity to engage the inner surfaces of the legs and bend them laterally thereby affixing the mounting device in the hole or bore and capturing the line in the stirrup.

A method for fixing an expansion anchor to a substrate includes introducing an anchoring zone and at least one part of a middle zone of a bolt of the expansion anchor into a hole in the substrate together with an expansion sleeve of the expansion anchor. The bolt is then moved relative to the expansion sleeve in a pull-out direction, as a result of which the expansion anchor is anchored to the wall of the hole. The space between the wall of the hole and the bolt is then filled to the height of at least one part of the middle zone with a curable mass such that the curable mass on the middle zone reaches up to an annular collar of the bolt, where the collar is configured as one piece with the bolt and is locally larger in cross-section, and the curable mass is cured.

An injector for filling an annular space formed around an anchor bolt includes a piston disk which has a through-opening for the anchor bolt and a quantity of curable compound mounted upstream of the piston disk, where the piston disk forms a piston for forcing at least some of the quantity of curable compound into the annular space.

A pair of latch members 36R, 36L in a case 20C protrudes from an outer face of the case 20C by a spring 38 and when the case 20C is passed through a wall hole 22H, the latch members 36R, 36L are narrowed by an engagement between outer edge (guiding) slant face 36ROI, 36LOI and a wall hole 22H and after the case 20C has passed through the wall hole 22H, the latch members 36R, 36L are spread by a spring 38 so as to engage the engagement slant faces 36RLI, 36LLI with the wall hole 22H and also while fixing temporarily the case 22C to the wall 22 together with a flange 20FL of the case 22C. After that, a screw 32 is screwed to draw the nut 34 toward the flange 20FL and to engage securely the latch members 36R, 36L held to the nut 34 with the wall hole 22H to complete secure fixing of the case 20C.
