The present disclosure provides an apparatus for forming orthogonal joints in conduits. The apparatus includes a first piece including a first plurality of curved openings and a second piece including a second plurality of curved openings. The apparatus includes a hinge configured to couple the first piece to the second piece and to enable the first and second pieces to be configurable in each of a closed position and an open position, where, when in the open position, the first piece is positioned adjacent to the second piece and, when in the closed position, the first and second pieces are configured to define a channel for receiving a conduit and each of the first plurality of curved openings is aligned with a corresponding one of the second plurality of curved openings. The apparatus further includes one or more magnets coupled to the first or the second piece.

A pipe boring device (1) including a housing (2)for receiving a self-tapping ferrule insert and a strap (3, 4) for securement around a pipe (10) to enable a hole to be bored into the pipe(10) by the ferrule insert. The strap (3, 4) includes first and second strap portions(3, 4) pivotally secured at a first of their ends (30, 40) by a connector (5). The first strap portion (3) includes a pair of slots (35a, 35b) along its length, which terminate at a second end (34) of the first strap portion (3) to form slot ends (36a, 36b). The second strap portion (4) includes three pairs of hooks (45a, 45b, 46a, 46b, 47a, 47b) along its length, which are receivable within the slots (35a, 35b) and configured to engage the slot ends (36a, 36b). The strap (3, 4) is configured to be wrapped around a pipe (10) with the first strap portion (3) overlapping the second strap portion (4) such that the second strap portion (4) is between the first strap portion (3) and the pipe (10) and one of the hook pairs (45a and 45b, 46a and 46b, 47a and 47b) is in engagement with the slot ends (36a, 36b). Each hook pair (45a and 45b, 46a and 46b, 47a and 47b) is spaced one from the next along the length of the second strap portion (4) such that the strap (3, 4) defines an opening for receiving the pipe (10) that is dependent upon which of the hook pairs (45a and 45b, 46a and 46b, 47a and 47b) is in engagement with the slot ends (36a, 36b).
