Claims
- 1. A plug for fixing to hollow and to solid building materials, comprising a plug body having a plurality of longitudinally extending expansible limbs that are expansible by screwing in of an expansion screw, said expansible limbs having a rear end and a leading end; a sleeve-shaped plug end which joins said expansible limbs with one another at said rear end and is formed so that the expansion screw is insertable through said plug end; a sleeve-shaped plug tip which joins said expansible sleeves with one another at said leading end and which is formed so that the expansion screw is screwable into said plug tip; and a stretchable material which joins said expansible limbs with one another circumferentially and which is pierced by several helically arranged slots.
- 2. A plug as defined in claim 1, wherein said plug end has a larger transverse dimension than in a region of said expansible limbs of said plug body and then said plug tip.
- 3. A plug as defined in claim 1; and further comprising at least two opposing anti-rotation ribs extending in a longitudinal direction and having a saw-tooth construction over a part of the length of said anti-rotation ribs, said anti-rotation ribs being arranged on an outer circumference of said plug body.
- 4. A plug as defined in claim 1, wherein said plug tip has non-rectilinear slots formed so that one arm of said slots is inclined in a direction of a lid of a thread of the expansion screw and another arm is inclined in an opposite direction.
- 5. A plug as defined in claim 1, wherein said plug body has a screw channel provided for the expansion screw and having inside said plug tip a cross-section other than a circular cross-section.
- 6. A plug as defined in claim 1, wherein said plug body has a screw channel which in a region of said plug tip has a flat cross-section.
- 7. A plug as defined in claim 6, wherein said screw channel of said plug body is slot-shaped.
- 8. A plug as defined in claim 7, wherein said screw channel of said plug body is formed by two intersecting slots.
- 9. A plug as defined in claim 1, wherein said plug tip has two opposing slots running in a longitudinal direction of said plug body and having a base spaced from a screw channel provided in said plug body for the expansion screw.
