Claim 11

The combination according to claim 5, 6 or 7, wherein said slotted element comprises a bar having an X-shaped cross-section, with peripheral flanges defining a rectangular prism, with one elongated slot in each lateral surface thereof.

Claim 12

The combination according to claim 5, wherein said slotted element has one major surface including means for securing said one major surface to a mounting surface, and a parallel major surface containing said slot therein, said slot providing access to said securing means.

Claim 13

The combination according to claim 10, wherein said major surfaces are circular.

Claim 14

The cap and member according to claim 1, wherein said member comprises a die-casting metal.

Claim 15

The combination according to claim 5, wherein said mounting part of said member has a square cross-section.

Claim 16

Adjustable mounting apparatus selectively engageable with a hollow element including in an external surface thereof a slot having a predetermined width, said apparatus comprising: a member selectively engageable with said slot, said member comprising: a body portion; a shank portion adjacent said body portion and having first and second peripheral surface parts parallel to an axis extending through said body portion, with said first part relatively close to said axis and the major portion of said second part relatively remote from said axis; and a head portion adjacent said shank portion, said head portion comprising (i) a mounting part having two parallel edges symmetrically disposed about said axis for engaging said slot, and (ii) an end part cooperating with said mounting part to form two shoulders adjacent said edges for retaining said member in said slot; and means for urging said shoulders against the edges of said slot to retain said member in engagement with said slotted element.

Claim 17

Adjustable mounting apparatus selectively engageable with a hollow element including in an external surface thereof a slot having a predetermined width, said apparatus comprising: a member selectively engageable with said slot, said member comprising: a body portion; a shank portion adjacent said body portion and having first and second peripheral surface parts parallel to an axis extending through said body portion, with said first part relatively close to said axis and the major portion of said second part relatively remote from said axis; and a head portion adjacent said shank portion, said head portion comprising (i) a mounting part having two parallel edges symmetrically disposed about said axis for engaging said slot, and (ii) an end part cooperating with said mounting part to form two shoulders adjacent said edges for retaining said member in said slot; and means for urging said shoulders against the edges of said slot to retain said member in engagement with said slotted element.

Claim 18
