Claim 1
Independent Claim
76 words
A fastener assemby for joining pipe ends, comprising a female member adapted to accommodate one pipe end, a male member adapted to accommodate another pipe end and insertable into said female member; at least two axially spaced abutment means respectively provided on said female and male members; and springy retaining means adapted to be snapped onto said members in contact with said abutment means, so as to prevent axial separation of said male and female members.
Claim 2
Dependent Claim
76 words
A fastener assemby for joining pipe ends, comprising a female member adapted to accommodate one pipe end, a male member adapted to accommodate another pipe end and insertable into said female member; at least two axially spaced abutment means respectively provided on said female and male members; and springy retaining means adapted to be snapped onto said members in contact with said abutment means, so as to prevent axial separation of said male and female members.
Claim 3
Dependent Claim
27 words
A fastener assembly as defined in claim 1, wherein said male member is adapted to be in frictional sliding engagement with said female member when inserted therein.
Claim 4
Dependent Claim
30 words
A fastener assembly as defined in claim 1, wherein said retaining means comprises openings into which the respective abutment means enter when said retaining means is snapped onto said members.
Claim 5
Dependent Claim
